Using the power of your mythic presence, you spur on allies even when all seems lost. Using this ability takes 10 uninterrupted minutes, during which time you give a stirring speech to all allies within 30 feet of you. If you expend one use of mythic power at the end of the speech, your allies gain a number of temporary hit points equal to your tier plus your Charisma modifier, and a bonus on saving throws against fear equal to half your tier (minimum 1). Any ally who currently has 1/4 of its full hit points or fewer gains twice as many temporary hit points from this ability. The temporary hit points and saving throw bonus last for 24 hours. Allies can benefit from this ability only once every 24 hours.
