As a Bonus Action - any creatures within 30ft of you that can hear you must make a charisma saving throw vs your character save DC(8+proficiency+CON or spellcasting if your class permits). On a failure, any hostile creatures must divert all of their attention to taking you down. For each creature that fails this save, you gain temp hp equal to half your character level. This temp HP can stack with other magical forms of temporary HP.
