Wall of Thunder

Spell — see Magic and Spellcasting for the rules and the Spell Index for the full list.

Arcane 3 Type: elemental (air), wall

Range: 120’ Duration: concentration

This spell conjures a wall of thunderous lightning and violent winds. The wall of thunder is 1’ thick and can be as large as 500 square feet. It can be almost any shape the caster desires, provided the entire wall is within the spell’s range and the bottom of the wall is in contact with the ground. The caster cannot evoke the wall that it appears on or on top of creatures or objects.

Any creatures that start their initiative or move within 5’ of the wall are subject to attack as if from a readied 2 HD monster. If the attack hits, the creature suffers 1d6 extraordinary electric damage. Any creature passing through the wall automatically suffers 2d6 extraordinary electric damage.

The wall does not block light, movement, or vision. It cannot be affected by physical or magical attacks and is invulnerable to physical and magical damage. If not destroyed, dispelled, or disintegrated, the wall remains so long as the caster maintain concentration on it. The concentrating caster can move the wall along the ground up to 20’ in any desired direction in range on his initiative each round.

Because wall of thunder draws its power from atmospheric winds, it can only be cast outdoors or in a well-ventilated room. It is primarily used during battles. An 8.25’ tall, 60’ wide wall of thunder can badly injure an entire company of troops by moving through them.
