Must be Goblinoid to learn this cantrip.

Immediately after an enemy creature has been dealt magical damage, you can use your reaction to target the lingering magic to deal additional force damage to the creature. The target creature must make a dexterity save equal to your spell save DC or take Force damage equal to your proficiency modifier.

At higher levels increase the amount of targets of the spell, 2 at 5th level, 3 at 11th level, and 4 at 17th level. A target can only be chosen once per round.
