JACK OF ALL TRADES

Type(s) Trait
Prerequisite(s) Trained in at least 8 skills all of which are Int, Wis, or Cha-based.

You are treated as trained in all Int, Wis, and Cha-based skills and apply a +1 proficiency bonus to them for skill checks (but not attack rolls or saving throws). This doesn't stack with an existing proficiency bonus if you're already trained in a skill.
Upgrade Each additional tier increases the proficiency bonus provided by this feat by 1 to a maximum of +4 at tier 4.
