Cohort of Chaos

Cohort of Chaos
Feat
Prerequisite: Level 4

You can channel cosmic forces of chaos to gain these benefits:
- When you roll a 1 or a 20 on an attack roll or a saving throw, the magic of chaos flows through you. Roll a d4 and consult the Chaotic Flares table to determine what happens. A flare lasts until the end of your next turn, and a new flare can't occur until after the first flare ends.
