You form a literal cannon made out of shimmering magical force that is immobile and automatically comes loaded with mana from casting this spell. As part of casting the spell, you can fire the cannon, dealing 5d8+CL (22+CL) force damage in a 10 ft radius at the point of impact (reflex halves).

You or any ally can spend 4 mana as a standard action to again fire the cannon at a new point (still using your CL). But the cannon can only fire once each turn.

You [mana burn] 4 mana while this spell is active. When the spell ends, the mana burn reduces to 1.

Upcast - For each additional mana spent, increase damage by d8 (4).
