Pistomnite

You summon a spectral cannon that unleashes a devastating 20-foot-radius explosive barrage. Creatures within the area must succeed on a Dexterity saving throw or take 6d6 force damage, halved on a successful save. The area becomes difficult terrain until the start of your next turn, making it harder for foes to maneuver. This spell is favored by Corsairs for its ability to disrupt and devastate Verdant Pact convoys.
