Mutagenist

You have become skilled in the creation and use of powerful mutagens that grant you enhanced abilities. You gain the following benefits:

You can create one mutagen during a long rest, using alchemical ingredients worth 200 gp. You can create different types of mutagens, each providing a unique benefit for 10 minutes. You can drink a mutagen as a bonus action. Once you drink a mutagen, you gain its benefits for 10 minutes, after which you gain levels of exhaustion. The levels of exhaustion are equal to the number of mutagens you've consumed since your last long rest.

Choose from the following mutagens:

Mutagen of Darkvision: You gain darkvision up to 120 feet and you can see through magical darkness and gain advantage on Wisdom (Perception) checks that rely on sight.

Mutagen of Nimbleness: Your speed increases by 20 feet and you can use your bonus action to Dash, Disengage, or Hide on each of your turns.

Mutagen of Resilience: You gain resistance to one damage type of your choice and your maximum hit points increase by your proficiency bonus for the duration of the effect.

Mutagen of Regeneration: At the start of each of your turns, you regain hit points equal to your proficiency bonus. Additionally, the amount of hit points you regain from potions, hit die, or effects other than mutagens is doubled.

Mutagen of Precision: You gain a +2 bonus to attack and damage rolls
