Tips and Strategies for Solving the Serum Puzzle in BO7 Zombies

One of the most challenging objectives in Call of Duty:Black Ops 7 Zombies takes place during the Ashes of the Damned main Easter egg. The Serum puzzle requires players to locate six unique biological components scattered across the map, many of which are locked behind specific upgrades, enemy conditions, or round requirements. Once collected, these items must be used to complete a high-risk laboratory challenge that tests both survival skills and puzzle awareness.

All Serum Part Locations in Ashes of the Damned

Serum Component 1:Powder of the Forgotten

This component requires two items:Wisp Tea and the Necrofluid Gauntlet.

Wisp Tea can be purchased at Zarya Cosmodrome, or obtained for free by completing the Twins Easter egg at Vandorn Farm. Once the tea is active, travel to the Tailor Shop in eastern Ashwood, located just to the right of the Vulture Aid perk.

Inside the shop is a mirror that reacts to Wisp Tea. Simply stand close to it while the effect is active, and the mirror will shatter. Afterward, equip the Necrofluid Gauntlet and shoot the broken mirror to cause the Powder of the Forgotten to drop.

Serum Component 2:Widow Lantern

Make your way to Blackwater Lake and enter the cabin nearby. Go downstairs into the kitchen and open the sink cabinet along the south wall to retrieve the Jar of Spores.

Next, bring the jar to Vandorn Farm. Just outside the main gate, you’ll find a dead horse covered in fungal growth. Interact with it to plant the spores. After three full rounds, the spores will fully mature, allowing you to collect the Widow Lantern.

Serum Component 3:Mysterious Limb

This item is tied to Zursa, the Elite zombie bear enemy that begins spawning from Round 16 onward.

To obtain the Mysterious Limb, Zursa must be killed using Ol’ Tessie’s Abomination Head Beam Attack. First, unlock the Abomination Head upgrade by visiting Reba Diner at Exit 115. Defeat the Cook zombie, collect the Freezer Key, and complete the Ol’ Tessie upgrade process in Ashwood.

Once Zursa appears, weaken her with standard weapons. When her health is low, finish her with the Beam Attack. If done correctly, she will explode and drop the Mysterious Limb.

Serum Component 4:Ravager Eyes

Ravagers are fast, four-legged enemies that can spawn randomly or during Max Ammo rounds. When one appears, lure it toward a Saw Blade trap, such as the one located outside the Barn at Vandorn Farm.

Activate the trap for 2,000 Essence and allow it to kill the Ravager. Upon death, it will automatically drop the Ravager Eyes.

Serum Component 5:Hoard Husk Chunks

This component also requires Ol’ Tessie to be equipped with the Abomination Head upgrade.

Drive Ol’ Tessie along the interconnected roadways and look for purple-glowing plants, which spawn at random locations. When you spot one, use the Beam Attack to destroy it. Doing so will cause the Hoard Husk Chunks to drop.

Be extremely cautious when exiting Ol’ Tessie after collecting the item, as zombie aggression in these areas is significantly increased.

Serum Component 6:Human Bones

Travel to the Barn at Vandorn Farm. You will need both a Combat Axe and a Molotov, both of which can be obtained for free.

The Combat Axe can be found in the Reba Diner kitchen, while Molotovs can either be crafted inside the Barn or picked up near Ol’ Tessie’s garage. Inside the Barn, locate the hanging corpse in the center of the room.

Throw the Combat Axe at the corpse’s right foot to sever it. Once it drops to the floor, throw a Molotov onto it. After the flames extinguish, you can collect the Human Bones.

After gathering all six Serum components, head to Yuri’s Lab, located southwest of Zarya Cosmodrome. Inside the lab, you’ll see six bowls arranged around the room, each holding one of your collected items, along with a chemistry station at the center.

Begin the sequence by interacting with the Powder of the Forgotten, which is placed in the fifth bowl. This triggers a lockdown and fills the room with smoke. Once the smoke clears, three Pigpen cipher symbols will appear on the chalkboard.

These symbols indicate the order in which the remaining bowls must be activated, starting with the top symbol, followed by the middle, and then the bottom.

During the lockdown phase, health regeneration is disabled. The only way to recover health is by using the Necrofluid Gauntlet siphon ability, which drains life from zombies when firing and reloading. Survive the lockdown while activating the bowls in the correct order to complete the Serum puzzle.

Practicing this entire process in Black Ops 7 Bot Lobbies is highly recommended, particularly for solo players. Bot lobbies allow you to rehearse timing-sensitive steps—such as the Zursa kill or the lab lockdown—without the added pressure of public matches. Some players even opt to buy CoD Black Ops 7 Bot Lobbies specifically to master Easter egg mechanics safely.

While the Serum puzzle may seem overwhelming at first, understanding each requirement turns it into one of the most reliable and repeatable steps in Ashes of the Damned. With preparation and patience, it becomes far less intimidating and far more rewarding.

Path of Exile: A Complete Guide to the Withered Debuff

Debuffs play a massive role in high-level Path of Exile gameplay, often serving as the difference between barely scratching endgame bosses and melting them in seconds. Among all the debuffs in the game, Withered is one of the most influential—especially for poison, chaos damage, and chaos DoT builds. When applied correctly, Withered becomes a powerful damage multiplier that dramatically boosts your ability to shred enemies with chaos-based skills.Unleash the power of purchasing POE currency through MMOexp and unlock endless possibilities!

Withered is a stacking debuff that causes affected enemies to take increased chaos damage. Each stack provides:

+6% increased chaos damage taken

Up to a cap of 15 stacks

Maximum of 90% increased chaos damage taken at full stacks

This bonus scales multiplicatively with many other forms of damage amplification, which is exactly why it has become a crucial mechanic for chaos builds across the game.

Many monsters and bosses can inflict Withered on the player. Since chaos damage bypasses energy shield unless you’re CI, getting Withered can be lethal if your defenses aren’t prepared.

How to defend yourself:

Aim for positive chaos resistance, ideally +60% or more

Use Chaos Inoculation for complete chaos damage immunity

Invest in armor, flasks, or crafted modifiers that grant “+% to Chaos Resistance”

Surviving chaos-heavy encounters becomes far easier when these layers are covered.

By default, each Withered stack provides 6% increased chaos damage taken. However, certain items, passives, cluster jewels, and modifiers grant “increased effect of Withered”, which boosts the value per stack.

How to Apply Withered in Path of Exile

There are numerous reliable ways to apply Withered, ranging from common skill gems to specialized uniques. Here are the main categories:

1.Skill Gems

    Several skills and supports are designed specifically to stack Withered:

    Withering Touch Support

    Grants a chance to apply Withered on hit

    Amazing for attack builds, minions, and fast-hitting skills

    Toxic Rain of Withering (Alternate Quality)

    Each pod hit can apply Withered

    One of the easiest ways to maintain stacks for bow users

    Wither Totems (Spell Totem + Multiple Totems Support)

    Classic strategy

    Rapidly stacks 15 Withered stacks on any enemy

    Very strong for chaos casters and bossing builds

    Skills that hit frequently or saturate an area with many hits tend to be the most reliable stackers.

    2.Unique Items

      A handful of uniques synergize extremely well with Withered or apply it automatically:

      Elder-influenced Swords: Can apply Withered on hit

      Ambush Mitts: Provide guaranteed Withered application in specific conditions

      Blackflame (Unique Ring):

      Converts ignite damage into chaos

      Extends the duration of Withered on enemies

      Central to many chaos-ignite hybrid builds

      Because of Blackflame’s unique mechanics, many players build entire archetypes around it.

      3.Passive Tree, Jewels, and Enchantments

        Additional Withered sources include:

        Glorious Vanity (Timeless Jewel):

        Can transform passives into “apply Withered” effects

        Labyrinth Helmet Enchants:

        Some enchants allow certain skills to stack Withered more efficiently

        Cluster Jewels:

        Especially those with “increased effect of Withered”

        Extremely powerful for scaling chaos DoT builds

        These sources help automate or enhance Withered stacking for endgame encounters.

        Maintaining Withered Stacks

        Withered has a base duration of 2 seconds, which means simply applying it isn’t enough—you must keep it ticking.

        Here are the most effective ways to maintain it:

        1.Stack Hits Through Attack or Cast Speed

          High hit frequency = more Withered stacks per second.

          2.Increase Skill Effect Duration

            More duration means fewer gaps between applications.

            3.Use Multiple Withered Sources at Once

              Relying on a single skill to apply Withered often leads to inconsistent stacks. Combining a totem setup with a skill gem, a unique item, or minions guarantees uptime on bosses.

              4.Occultist: The Easiest Way to Guarantee Max Stacks

                The Withering Presence ascendancy passive:

                Automatically applies a stack every second

                Each stack lasts 15 seconds

                Requires no button presses or additional investment

                For chaos-damage casters, this is one of the strongest QoL ascendancy nodes in the entire game.

                While Withered does not directly lower chaos resistance, it effectively performs the same function by increasing chaos damage taken—allowing builds to pierce through enemies with naturally high chaos resistance.Don’t wait for victory—buy your cheap POE currency and start ruling the kingdom!

                Withered remains one of Path of Exile most impactful debuffs, acting as a massive damage multiplier for any build that leans into chaos or poison. Understanding how it works, how to scale its effect, and how to maintain stacks consistently will significantly increase your endgame damage output. Whether you use totems, skill gems, unique items, or ascendancies, mastering Withered is essential for pushing high-tier content and claiming fast boss kills.

                Path of Exile 2:Step-by-Step Walkthrough to Unlock Navali Rest Mana Upgrade

                Path of Exile 2 expands nearly every aspect of the original ARPG-from the new class archetypes and refined skill systems to immersive side quests that reward careful exploration. One of these hidden treasures is Navali Rest, a secret Act 4 objective that permanently increases your character maximum mana by 5%. While the bonus itself is subtle, its lasting impact makes it an essential discovery for any player looking to optimize performance, especially in mana-dependent or hybrid builds.

                However, the location of Navali Rest is easily misunderstood, leaving many Exiles searching in the wrong area. Every permanent stat boost in Path of Exile 2 contributes to your character overall power, but mana in particular plays a vital role across multiple archetypes. Whether you’re spamming high-cost abilities or maintaining multiple auras, an extra 5% maximum mana scales far beyond early-game value.

                Here’s how the bonus helps various playstyles:

                Spellcasters:Larger mana pools allow for smoother rotations, uninterrupted channeling, and better synergy with mana-based uniques or crafted gear.

                Melee and Bow Builds:Even physical-oriented characters rely on mana for dashes, warcries, or buff skills. Extra mana ensures these remain available during intense fights.

                Endgame Optimization:When combined with crafted gear, flasks, and passive nodes, the 5% boost becomes a permanent part of your scaling equation-small, but meaningful.Unlock endless possibilities with the power of POE 2 Currency purchased with MMOexp!

                Simply put:skipping Navali Rest means leaving power on the table.

                Many players initially assume Navali Rest is located near the Hall of the Dead, due to misleading world map placement in Act 4. In truth, the resting place of Navali lies deep within the Eye of Hinekora, a separate area unlocked later in the act.

                Step-by-Step Location Guide:

                1.Enter the Eye of Hinekora once it becomes accessible (details below).

                2.Fully explore the zone-its layout changes with each instance.

                3.Look for a checkpoint that leads into a wide, quiet hall.

                4.Follow the corridor until you reach a small chamber at the far end.

                5.Inside, you’ll find a jade-encased coffin holding Navali body suspended in midair.

                Interacting with the coffin and selecting “Pay Your Respects” will immediately grant your character the +5% Maximum Mana bonus. Afterward, a short dialogue with Navali reveals additional lore, giving the moment an emotional touch for long-time fans of Wraeclast enigmatic soothsayer.

                Unlocking the Eye of Hinekora

                You won’t be able to access Navali Rest right away-the Eye of Hinekora is tied to several key story milestones in Act 4. To reach it, follow these steps:

                1.Complete the Isle of Kin:Progress naturally through this major Act 4 area.

                2.Defeat Krutog, Lord of Kin:This boss uses heavy fire attacks and summons reinforcements-bring fire resistance and mobility skills.

                3.Free Matiki:After Krutog defeat, you’ll release Matiki and advance the storyline.

                4.Trigger “Trial of the Ancestors”:This quest sets the stage for the Eye of Hinekora.

                5.Speak to Makoru:He’ll grant access to a new chain of islands-the first being the Eye of Hinekora.

                Once this sequence is complete, you’ll be able to enter the Eye of Hinekora and begin your search for Navali resting place.

                Because maps in Path of Exile 2 are procedurally generated, finding Navali chamber can vary wildly from player to player. Use these tips to save time:

                Explore Beyond Quest Markers:The chamber rarely lies along the main story path-check side routes and dead ends.

                Watch for Long Empty Halls:These often lead directly to hidden side rooms.

                Use Checkpoints Strategically:Navali Rest usually appears near one, so scout nearby after activating a checkpoint.

                Don’t Confuse It with Trial Entrances:The Eye of Hinekora contains trial doors related to the Hall of the Dead, but Navali Rest is an entirely separate point of interest.

                Veteran players aiming for faster Act 4 progression often use cheap Path of Exile 2 Currency trading to streamline gear upgrades and travel efficiency-though optional, it helps make exploration smoother.

                Navali Rest is more than just a minor stat increase – it’s a hidden tribute to one of Wraeclast most beloved characters and a permanent edge in your build resource pool. Despite the confusing map placement, knowing it’s located within the Eye of Hinekora ensures you won’t miss it.

                By following the Isle of Kin questline, unlocking the Eye of Hinekora, and thoroughly exploring its winding halls, you’ll not only gain a permanent 5% Maximum Mana boost but also uncover a meaningful piece of Path of Exile 2 lore.

                For anyone aiming to conquer the game brutal endgame challenges, completing Navali Rest isn’t optional-it’s a rite of passage.

                Diablo 4 Season 10 PTR:Top Builds for Every Class

                The Season 10 PTR in Diablo 4 has upended the balance of Sanctuary, introducing bold new mechanics, Chaos Armor synergies, and powerful legendary effects. While the meta is still in flux and Blizzard may tweak things before launch, early testing already highlights which builds are emerging as the strongest contenders.

                Some classes, like Hydra Sorcerer and Twisting Blades Rogue, remain reliable, while others—such as Necromancer Shadow Blight and Spiritborn Jaguar Thorns—are surprising sleeper hits. However, not all classes are equally strong yet, and a few may need adjustments.

                1.Barbarian – Whirlwind / Mighty Throw Hybrid

                  Barbarians continue to dominate with raw, relentless power. The new Sabre of Tsasgal has sparked a shift toward a hybrid build combining:

                  Whirlwind for clearing enemy waves,

                  Mighty Throw for heavy-hitting elites, and

                  Hammer of the Ancients for boss destruction.

                  This versatile setup excels in both open-world farming and endgame dungeons, offering satisfying flexibility and strong performance. It’s shaping up to be the defining Barbarian build of Season 10.MMOexp delivers Diablo 4 gold directly to your vault quickly, securely, and affordably.

                  2.Druid – Rotting Lightbringer Pulverize

                    Thanks to Chaos Armor, Druids are experiencing a major resurgence. The Rotting Lightbringer Pulverize build benefits hugely from the ability to slot legendary powers in unexpected gear pieces.

                    Now, Lightbringer can be equipped in gloves or other armor slots, freeing Druids to wield another high-powered weapon such as The Grandfather, stacking damage even further. This upgrade makes Pulverize a devastating, chaos-enhanced force in both PvE and high-end content.

                    3.Necromancer – Shadow Blight

                      Among Necromancers, Shadow Blight is standing out as the PTR’s most powerful option. While builds like Blood Wave and Lidless Wall Bonestorm remain effective, Shadow Blight has soared thanks to recent buffs.

                      The synergy allows Necros to hit astronomical damage numbers—potentially billions or trillions under ideal conditions. Coupling this with Ebonpiercer and Reaper Pursuit ensures consistency, making Shadow Blight a dominating build for high-end farming and boss encounters.

                      4.Rogue – Twisting Blades

                        Rogues remain slightly behind the curve this season. PTR testing shows that new Chaos Perk setups, including Reload Rogue, haven’t delivered a major breakthrough.

                        Nevertheless, Twisting Blades Rogue continues to be the most reliable option. Its fast-paced, fluid combat style and returning blade AoE bursts make it a solid pick for players who prefer agile, skill-intensive gameplay.

                        5.Sorcerer – Hydra

                          Despite hype around Lightning Sorcerers in Season 10, Hydra Sorcerer remains the most dominant build. With Chaos Armor, Sorcerers can now equip multiple Hydra-boosting amulets simultaneously, pushing damage and efficiency into absurd levels.

                          Hydra swarms are exceptional for both boss fights and clearing large maps. The build scales naturally without requiring complex micromanagement, making it arguably the single most overpowered build on the PTR so far.

                          6.Spiritborn – Jaguar Thorns

                            The new Spiritborn class has already produced an impressive standout:Jaguar Thorns.

                            By combining Aspect of the Plains with Balazan Maxtlatl, Spiritborn can unleash massive thorn-based counterattacks that decimate enemy packs in The Pit. While this build looks powerful, PTR testing means Blizzard may balance it before the season goes live.

                            While the Season 10 PTR is still evolving, these six builds represent the current pinnacle for each class.Instead of wasting countless hours farming for Diablo IV Items for sale, choose MMOexp for a fast, secure, and affordable gold delivery.Whether you prefer the raw destruction of a Whirlwind Barbarian, the overwhelming Hydra dominance of a Sorcerer, or the thorny risk-reward of Jaguar Spiritborn, Season 10 promises one of Diablo 4 most diverse and chaotic metas yet.

                            Understanding Cobalt in Skull and Bones

                            In Skull and Bones, cobalt is one of the most important resources for players aiming to upgrade their ships and strengthen their naval power. This versatile metal plays a critical role in crafting essential ship parts and boosting your overall performance in battles at sea. Whether you’re gathering it firsthand or buying it from traders, knowing how and where to get cobalt is key to maintaining an edge on the high seas.

                            Why Cobalt Matters

                            Cobalt is a durable and valuable metal used extensively in ship upgrades. As you progress through the game, the need for higher-quality materials grows, making cobalt indispensable for reinforcing your vessel and outfitting it with advanced components. Without enough cobalt, it becomes harder to compete against rival players and formidable AI enemies.

                            How to Acquire Cobalt

                            There are two main avenues to obtain cobalt in the game world:

                            Purchasing from Merchants

                            Mining from Ore Deposits

                            Buying Cobalt from Merchants

                            Scattered across the map are various merchants who sell cobalt. Their inventories change regularly, with prices fluctuating based on the game’s economy and supply. Players who want quick access to cobalt can seek out these vendors, but they must be ready to monitor prices and stock closely.

                            Keep in mind that merchant availability and cost depend heavily on location and current market conditions. Smart buyers will shop around to find the best deals and may choose to stockpile cobalt when prices dip.Every great pirate needs the right tools – get your Skull and Bones Items with MMOexp today!

                            Mining Cobalt Ore

                            Mining is the most dependable method to gather cobalt. The richest cobalt ore deposits are located in the northwest section of the map, especially near the Sunken Gold Mine Outpost. This outpost serves as a central hub for resource collection and is marked clearly on the map, making it easy to find.

                            Just north of this outpost, you’ll discover clusters of shimmering cobalt ore deposits ready for mining. Using the right tools and upgrades, players can extract large quantities of cobalt to fuel their crafting and upgrading needs.

                            Tips for Efficient Cobalt Gathering

                            To get the most out of your cobalt hunts, consider these strategies:

                            Visit Merchants Often: Make it a routine to check different vendors around the map. Some may offer cobalt at lower prices, letting you save silver while stocking up.

                            Upgrade Your Mining Gear: Better mining tools increase the amount of cobalt you collect per deposit, making your resource runs more productive.

                            Team Up With Others: Coordinate with friends so one player mines while others scout for threats or additional deposits. Cooperation improves safety and efficiency.

                            Learn the Map: Familiarize yourself with outposts, ore locations, and resource hotspots to plan quicker, more effective routes.

                            Watch Market Trends: Keep an eye on cobalt prices. Buying in bulk during a price drop can stretch your silver further.Get the best cheap Skull and Bones Silver from MMOexp today and rule the seas like a true legend!

                            Cobalt is a cornerstone resource in Skull and Bones, essential for any player serious about ship upgrades and survival on the seas. Whether you choose to mine it yourself or purchase it from savvy merchants, mastering cobalt acquisition will help you maintain a competitive advantage.
