You are a craftsperson who can make a variety of concoctions.

Basic Alchemy

Upon choosing this archetype at 3rd level, you gain proficiency with Alchemist's Tools. You may use them to craft known recipes as well as create new potions, poisons, and other mixtures.  Creating these things has a time and monetary cost.

Alchemy

At 3rd level, you know the formulas for a few basic alchemical mixtures.  You learn more recipes at 7th, 10th, and 15th levels as detailed in the chart below.  Each formula takes time to make and require an amount of gold in order to gather the necessary materials, components, vials, etc.  Each formula also has a mishap score.  When making a formula, make an Alchemy check (d20 + your Intelligence modifier + Proficiency bonus) if the roll is equal to or lower than the mishap score, the formula fails using up all materials and time it took to attempt it.  Roll on the mishap table to determine what happens.

In addition, you may attempt to create and discover new combinations and formulas.  To do so, explain to your GM exactly the effect you are attempting to create with your mixture.  They will then decide the appropriate cost, time commitment, and mishap score for such a concoction.  New formulas are harder to create than known formulas so the cost, time, and mishap score of discovering a new recipe should be about 1.25 times more than a comparable formula from the list below. Once successfully discovered, the formula costs can be reduced for future crafting.
