Leader of the People

You can spend up to 10 minutes giving an inspiring speech to all allies within 100ft, preparing them for a battle to come and steeling their will for the fight ahead. All allies in range gain 2d10+your level+CHA modifier in temporary hit points, are immune to frightened, have advantage on Wisdom & Constitution Saving throws and receive one use of Relentless Will. Relentless Will, when used, restores the ally to 1 hit point when an attack reduces them to 0 hit points. This feat can only be used once every 7 days.
