Hell of 1,000,000 Needles
Metal filaments erupt across a wide cube, impaling and pinning anyone caught inside while lightning arcs through the field.
The landscape fills with monumental filaments of metal. The needles lance into a cube 30 feet on a side within 500 feet. Each creature in the area takes 13d6 piercing damage, with a basic Reflex save against your class DC. Each creature that fails its save is impaled, becoming Immobilized until it Escapes (the DC is your class DC); a creature that critically failed is also Off-Guard as long as it's impaled.
The hell remains until the end of your next turn, but you can Sustain it up to 1 minute. Using this impulse again ends any previous one. The first time you Sustain it each round, lightning crisscrosses the needles. Each creature in the area takes 3d12 electricity damage with a basic Reflex save against your class DC. Squares in the area are hazardous terrain. A creature takes 6 piercing damage for every square of the area it moves through.
Level (20th) The initial damage is 17d6, and the hazardous terrain damage is 7.
