Alaric’s taunting imp

An small imp like demon appears in an unoccupied space of your choice within range and lasts for the duration. The imp attacks anyone (including friends or even the caster) that comes within 5 feet. The creature takes 2d6 magical slashing damage on a hit.  In addition if the imp hits it unleashes a string of vile insults giving the person hit disadvantage on all attacks against any other target for as long as the imp persists.  The imp has an AC equal to 13 + the casters spellcasting modifier.  If hit the imp exploded doing 2d6 fire damage (Dex save against the casters spell DC for half damage) to all creatures with 10 feet and the spell ends.

while the imp persists, the caster can speak and understand infernal.  The imp continually speaks to the caster in infernal - knowingly discussing past sins of the caster (real or made up as the DM dictates)

As a bonus action, you can command the imp to move up to 40 feet and attack a creature. Any such commands must by spoken in infernal and os a volume that allows the imp to hear.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd
