La Verdea

You enchant your arrow with volatile energy, causing it to detonate upon impact. The arrow explodes in a 10-foot radius upon hitting a target or surface, dealing 3d6 fire damage to all creatures in the area. Creatures in the radius must make a Dexterity saving throw. On a success, they take half damage. The explosion leaves a scorched area, creating difficult terrain until the end of your next turn.
