Alchemical items include magical medicines, potions, poisons and concoctions made from not only plants, but caustic chemicals, acids and what some might consider dangerous or illegal substances.

Proficiency with these supplies allows you to add your proficiency bonus to any Intelligence checks you make for your alchemical concoctions.

Crafting Alchemical Items

To craft an alchemical item, you must have proficiency in the use of alchemist's supplies and you must know the recipe for the item you wish to craft. After choosing the item to craft, you then must gather the required ingredients and then begin crafting the item.

Alchemical items come in three qualities: Minor, Moderate, and Masterwork. Generally, the higher the quality, the more potent the item. Alchemical items do not lose their potency unless they are purposely mixed with other ingredients like water. Many alchemical items and recipes may be purchased from local alchemists, but as these items may take a while to produce, they could be very expensive when purchasing.

Alchemy Recipes If you know the recipe for a particular item, you know which ingredients are required to craft an alchemical item, where those ingredients are likely to be found, and how to prepare them. You even know enough to substitute ingredients based on what’s available in the local area. Every alchemy recipe specifies the DCs required to craft Minor, Moderate, and Masterwork quality versions of that item. It also specifies any unique ingredients you must have access too. Those ingredients must be acquired through special means, either through purchase or during the course of an adventure.
