Craft real potions
Drop ingredients into the cauldron and strike the recipe map with a steady hand — where your cursor lands decides the potion's type and its strength.
Brew potions. Defend the wall.
A blight spreads from the heart of a cursed kingdom, and only your fortress stands between the horde and the lands beyond. You are the alchemist on the wall — and your potions are the last line of defense.

How it plays
Craft in the lab. Fight on the wall.
Alchemy Lab fuses hands-on potion crafting with real-time tower defense. Work your cauldron, then unleash what you brew to hold the line against waves of monsters.
Five ways to fight
Heal your tower, strike the enemy, raise a physical shield, ward off magic, or empower your defenses. Time slows when you choose — but it never stops.
Defend your fortress
Waves march from the gloom toward your wall. Level up your alchemist and reinforce the fortress to survive escalating assaults and boss encounters.
75 levels, 6 cursed regions
From the misty Blightwood and the war-scorched Ashen Front, through poison swamps and frozen wastes, into an arcane dead city, down to the lava of the Maw.
Grow your alchemist
Earn XP from every craft and every battle, level up, and invest points across potion ladders and fortress upgrades. Your power grows with the threat.
