Antisocial Distance

This lumpy black and brown rod is mildly uncomfortable to hold.  As a bonus action, a spellcaster can expend a spell slot into the rod. Any creature within 5 feet of the spellcaster must make a Strength saving throw against the caster's spell save DC or take Force damage equal to 1d4 per spell slot level and be pushed 10 feet back per spell slot level expended.
