Cursed Flick

Flick with any hand and fingers to send a small bolt towards a target. The bolt deals 1d4 damage and is guaranteed to hit the target. It then immediately returns to the caster, who must then make a successful dexterity check to catch the bolt, and then use a bonus action to throw it back at the target. The bolt will return at the start of the next round, and the caster must repeat until failed dexterity check, or until the bolt is not thrown. On a failed dexterity check or not throwing the bolt, the bolt blows up in the caster's hand for 1d4 damage. The bolt must be thrown at a living target.
