Descripción
Your strike cause ambient magic surrounded a creature to collapse and detonate. The target hit by the strike takes an extra 4d6 Force damage from the attack. If the creature is Concentrating on a spell, that Concentration is broken.
In addition, each ongoing spell of level 3 or lower on the target ends. For each ongoing spell of level 4 or higher on the target, make an ability check using your spellcasting ability (DC 10 plus that spell's level). On a successful check, the spell ends.
