Boon of Defiant Soul

Epic Boon Feat

You have reached the pinnacle of the Soul Siphon discipline, preserving your soul through forces that would destroy an ordinary life.

You gain the following benefits.

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 30.

Soul's Defiance. When you would be reduced to 0 Hit Points or an effect would kill you outright, you can drop to 1 Hit Point instead and gain a new source of 50 Temporary Hit Points. You can then cast Soul Split as a Reaction without expending a spell slot, creating two duplicates instead of one. Once you use this benefit, you can't use it again until you finish a Long Rest.
