A swirling dark cloud of metal shrapnel spins through the air toward you, accompanied by a shrill grinding noise. Arcs of lightning flicker within the metallic swarm.
A shredstorm is a swarm of thousands of bladed disks crackling with electricity. Each disk is a magically animated adamantine saw blade, roughly the size of a shuriken, spinning at tremendous speed. The magical ingredient in their creation that allows them to fly binds them together into a cohesive creature that can be commanded as one by its creator.
Shredstorms are constructs designed for use on the battlefield to breach enemy fortifications and eviscerate defenders. Commanders deploy them to rip through walls, opening a passage for allied troops, or else to simply slip into a castle and begin wiping out defenders from behind their lines.
Each individual disk that makes up a shredstorm is 4 inches in diameter and weighs about 2 ounces.
Shredstorms do not speak.
A shredstorm follows the commands of its creator if that individual is within 120 feet; if uncommanded, it follows its last orders to the best of its ability. Its creator can give it simple programs that the construct follows in its creator’s absence, such as “Enter the fortress and attack anyone inside.”
Due to its deadly nature and electrical aura, a shredstorm deals 4d6 points of damage plus 2d6 points of electricity damage to any creature whose space it occupies at the end of its move.
Lightning Bolt (Su): A shredstorm can discharge part of its electrical aura in a blast of electricity that acts as a lightning bolt cast by a 14th-level caster (Reflex DC 17 half). A shredstorm requires 2d6 hours after each use of this ability to build its electrical levels back up to full strength; during this time, it deals only 1d6 points of electricity damage to those whose space it occupies. The save DC is Charisma-based.
Penetration (Ex): The swarm attack of a shredstorm is treated as an adamantine magic weapon for the purpose of overcoming damage reduction, and it strikes incorporeal creatures as a magic weapon does. When striking an object, a shredstorm ignores any hardness less than 20.
