The Weak Ones Would Just Keel Over and Die...

The spirit of Michael Rosen embraces you. Upon muttering the words "The weak ones would just keel over and die" all enemies in an 100 ft. radius sphere centered upon you that have a challenge rating of 2 or less must make a DC 10 Wisdom saving throw. On a failed save, they instantly die. On a success, they gain advantage on attack rolls for 1 round in combat.
