Arcane Grenade (Recharge 5–6).

Throws a device to a point within 60 feet. Each creature in a 10-foot radius must make a DC 13 Dexterity saving throw, taking 2d6 force damage and being pushed 10 feet on a failure (half damage on success).

The artificer powers up a weapon. Until the end of the turn, its weapon attacks deal an extra 1d4 lightning damage.
