Potent Potioneering

The Wild Alchemist pushes their Science to the edge, bordering on brilliance and disaster. They craft Potions and Elixirs with interesting side effects.

The Wild Alchemist can create a number of Potions or Elixirs per long rest equal to their Intelligence Modifier. The type of Potions they can create are determined by their level, Common potions at 3rd level, at 5th level they can brew Uncommon potions, at 9th level they can brew Rare potions, at 15th level they can brew Very Rare potions. They can brew these potions by either taking a minute or expending a spell slot of the appropriate level as an action, a 1st level spell for Common potion, a 2nd level spell for Uncommon potion, a 3rd level spell for a Rare Potion, and a 4th Level spell for a Very Rare Potion. You can use a higher level spell slot to make a potion than is required, but there is no additional effect.
