Monks of the Way of the Chemist pioneer a style that focuses on mastery of the body through chemical enhancements. Scorned by most orders, these monks regard the body like a machine, to be perfected by careful experiment and adjustment - they are scientists at the core rather than mystics.
Starting at 3rd level, you may use your intellect instead of your wisdom for the purposes of you Unarmored Defense class feature. Likewise, the save DC against your ki features is equal to 8 + your proficiency bonus + your Intelligence modifier. If the Multiclassing optional rule is available to you, you may take another class only if you have at least 13 Dexterity and 13 Intelligence, but the requirement for 13 Wisdom is removed.
Also at third level you gain proficiency with herbalism kits. During a short or long rest, you may prepare two chemical vials, choosing from among the following options:
These vials remain viable until your next short or long rest. As a bonus action, you may consume one of these vials, which has the same effect as if you had cast the spell in question on yourself. The chemical affects only you, and its effect cannot extend past the end of your next short or long rest. At higher levels, you gain access to more options:
When you reach 6th level, you learn to manipulate your adrenal glands with your Ki. On your turn, you may spend 2 Ki to take one additional action on top of your regular action and a possible bonus action.
Once you use this feature, you must finish a short or long rest before you can use it again.
At 11th level, you learn to create a chemical that can make you mentally more keen. When you are preparing your elixirs, you may also prepare two vials of Cognitive Enhancement. For ten minutes after consuming one of these vials, you make all intelligence and wisdom checks with advantage, and you gain a +5 bonus to your passive perception and investigation skills.
When you reach 17th level, your control over your own perceptions reaches astonishing heights. You have advantage on all perception checks and your passive perception is increased by 5.
You may spend 1 ki point during your turn to accelerate your perception of time until the start of your next turn. While in this state, all attacks against you have disadvantage, and you may use your reaction to make an attack against any creature that performs an attack while in your reach.
