Alchemy

Alchemy is a skill that all Slayers practice in some capacity. By referencing to Zaos Aeris' Herbarium, one can use ingredients such as a natural herbs to create potent concoctions. While many Slayers formulae remain closely guarded secrets, some potions can be learned and crafted by those that wanted to learn.

The potency of an alchemical creation is largely determined by the skill level of the crafter and the complexity of the potion involved. Alchemy is intelligence/wisdom-based. Proficiency with an alchemy or poisoner's kit allows you to add your proficiency bonus to the ability check to determine the quality of the end result. Depending on the complexity of the potion, a certain DC must be met in order to produce the proper potion. Failing the DC by a large amount can produce more than useless slime, while exceeding the DC by a large margin can produce a more potent variant potion, or an increased amount of potions.

As with other skills, homing the art of alchemy can increase one's mastery over time, improving the skill's efficacy. Even a novice that practices enough can eventually become proficient with alchemy tools, and a proficient potion maker can eventually become an expert.
