The alchemist mixes herbs found by Herbalism and reagents in order to generate elixirs, potions, oils, flasks and cauldrons with a variety of effects. A player can create healing, invisibility, elemental resistance and mana potions; oils to coat weapons; and much more.
Alchemy is useful to all character classes. Melee fighters can use alchemy to create buff and healing potions. Spell casting classes can use alchemy to create mana potions and related buffs. You can create potions for yourself, sell them to others, or give them to your party members and friends. Alchemists are well loved when they hand out potions.
