From publisher blurb:
The Alchemist comes to the Blood & Treasure system: not just a paragon of scribing scrolls and brewing potions, and liberated from endless drudgery in the service of overweening Magic-Users, the Alchemist is a competent spell caster in their own right and the ultimate crafter of magic items! They are also creators of poisons, acids, and charms formed from the essence of beasts and monsters
Alchemists are a diverse bunch, and can choose from four unique traditions: Arcane (skilled spell casters and pseudoscientific makers of magical explosives), Divine (sanctified temple-builders and makers of Golems), Natural (practitioners of Druidic magic and students of the wild) and Psychological (eccentrics who treat their own body, mind and soul as items to be transformed).
