Pursue The Truth

You gain proficiency with alchemist supplies. If you already have this proficiency, you gain proficiency with one type of artisan's tools of your choice.
In addition, you gain proficiency in one of the following skills of your choice: Medicine, Investigation, Insight, or Deception.
When you make an Intelligence check using alchemist's supplies, a herbalism kit, or one of the skills chosen through this feat, you can roll 1 Repression Die and add it to the result.
You can use this benefit a number of times equal to your proficiency, and you regain all expended uses when you finish a long rest.

NOTE: This feat is made to be used with the homebrew Artificer class: Doctor Of The Dual Soul
