Alchemy is a craft. Any character with the Alchemist subclass can use this system, mixing ingredients to create drinkable potions and throwable tinctures with tier-scaling effects.
To produce potions and tinctures, roll 1d20 + Reasoning + ((Dexterity OR Ether) / 2) against the Tier DC.
Success: the potion or tincture is produced normally.
Failure: the ingredients are completely lost.
Critical Success: create 1 additional potion or tincture with the same ingredients.
Critical Failure: everything explodes catastrophically and deals 1d30 area damage to allies and enemies.
