Tier I battle potions are not in the tech tree: you learn them by brewing the right runes in the lab.

Tier II formulas come from technology research; wikily.gg lists tier III as learned by brewing again.

Each brew costs 1 Alchemy Flask and fuel, like any alchemy craft.

The Alchemist sells all four tier I potions from the start of the game; Healing Potion II joins at shop level 2.

The quest First... Sludge? also hands you 2 Healing Potions.

Potions stack to 20 and fit in a potion bag, universal bag or big universal bag.

Healing is the safety net. Damage and Berserker both pay off with a strong sword, because their bonuses ride on each hit and each swing.

If your squad does the fighting, Zombie Motivator doubles its attack rate instead.

Brewing 25 potions earns the Novice Alchemist achievement — see our trophy guide.
