Concussion Grenade

As part of the action used to cast this spell, you must make a successful ranged attack with a weapon against one creature within the spell’s range. The spell fizzles out beyond 30' but the original projectile can still do normal damage if it hits. If the attack is successful within the 30' range, the target suffers the attack’s normal effects, and a wave of concussive force explodes from the point of impact, inflicting force damage equal to your spellcasting ability modifier to all creatures (friend or foe) within 5'.

The spell's force damage increases to 1d4 + your spellcasting ability modifier when you reach 5th level. Both damage rolls increase by an additional 1d4 at 11th level and 17th level.
