Psychic Fortitude

Drawing from the bottomless well of the Warp, you reach out with your mind to bolster your allies’ force of will with your own. Choose a number of allies (excluding you) up to the SL of your Manifest Test within Short Range. Until the start of your next turn, the targets may use your Willpower score in place of their own when making Willpower Tests, and they have Advantage on Willpower Tests.
