The Bazaar Zosima Guide: Mak Skills and Reroll Costs

Who Is Zosima in The Bazaar?

The Bazaar Zosima encounter offers a free skill that can strengthen Mak’s build without cutting into your gold. Zosima is a Diamond-tier trainer who teaches Mak-specific skills. You can choose only one, so match the reward to the items doing the work on your board.

Despite appearing alongside hero-related content, Zosima is a skills merchant rather than a playable hero. The encounter’s value comes from adding effects that support Mak’s Potions, Poison, Relics, Regen, or Lifesteal weapons.

Free Skill Selection and the 8-Gold Reroll

In patch 20.1, Zosima’s encounter uses these selection rules:

Image: Steam / Tempo

• Choose one skill: You can take only one skill from the encounter.
• The selection is free: Taking a skill costs no gold.
• Reroll once: You can reroll a single time for 8 gold.
• Leave without choosing: You can exit without taking a skill.

Compare the initial offers against your current board before paying for the reroll. Check whether each skill has the item types and triggers it needs: a Potion effect needs Potions, while a Lifesteal weapon effect needs weapons with Lifesteal.

Spend the 8 gold only when you want another chance at a better fit. The payment buys a reroll; it does not guarantee a particular skill. Once you have used it, there is no second reroll in this encounter.

Biohazard and Brewmaster Explained

Biohazard and Brewmaster are two Diamond-starting skills associated with Zosima. Their effects support different combat plans.

Image: Steam / Tempo

Skill	Starting Tier	Effect
Biohazard	Diamond	Doubles the enemy’s Poison the first time you fall below half Health each fight.
Brewmaster	Diamond	Gives a Potion +1 Multicast at the start of each fight, lasting for that fight.

Biohazard: Build Poison Before the Health Trigger

Biohazard activates when your Health first drops below half during a fight. Its payoff depends on the Poison already on the enemy when that happens.

Pair it with a board that applies Poison before you cross the Health threshold. A larger existing stack gives the doubling effect more to work with. Avoid selecting it solely because your build needs damage; the skill depends on an existing Poison stack.

The trigger happens only the first time you cross that threshold each fight. Do not plan around repeatedly dropping below half Health to activate it again.

Brewmaster: Add Multicast to a Potion

Brewmaster gives a Potion +1 Multicast when combat begins. That bonus lasts for the fight.

Check your Potion lineup before choosing it. Keep the distinction between Multicast and Ammo in mind: Brewmaster grants Multicast, while other Potion skills change Ammo or cooldowns.

Match Other Skill Offers to Your Board

Zosima’s options extend beyond those two skills. Read the condition before comparing the payoff.

Image: Steam / Tempo

For a single-Potion setup, look for the skill that grants your only Potion +1 Max Ammo and halves its cooldown. Count your Potions before taking it: the effect requires exactly one.

For broader Potion support, other effects include reducing Potion cooldowns by 1 second or granting additional Ammo. Compare those effects with the specific limitation your board needs to address.

For Lifesteal weapons, options include a 1-second cooldown reduction and an effect that uses your Lifesteal weapons the first time you fall below half Health each fight. Check the full item requirement; a Lifesteal item does not automatically satisfy a condition that specifically calls for a Weapon.

For Regen and Relic setups, look for effects that add item damage equal to your Regen, activate Relics at the half-Health threshold, or reward repeated Relic use. Another effect reduces the cooldowns of Relics and Tools by 5% or 10%. Count the qualifying items already equipped before committing your one selection.
