Emrys' Forceful Fulmination

You mentally choose a point that you can see within range, and strike the bell with the hammer. The point erupts in a wave of force energy. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 force damage on a failed save, or half as much damage on a successful one.

The shock wave is blocked by walls but does normal damage to creatures in water. It shatters fragile objects in the area that aren't being worn or carried. Effects which grant immunity to Magic Missile (such as those under the protection of a Shield spell, or wearing a Brooch of Shielding, for instance), reduce the damage from this spell to zero.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
