Range 30 feet; Area 1 5-foot square; Saving Throw Reflex; Duration sustained up to 1 minute
You create a sphere of flame in a square within range. The sphere must be supported by a solid surface, such as a stone floor. The sphere deals 3d6 fire damage to each creature in the square where it first appears; each creature must attempt a basic Reflex save. On subsequent rounds, you can Sustain this Spell, leaving the sphere in its square or rolling it to another square within range and dealing 3d6 fire damage; each creature in its square must attempt a basic Reflex save.
Creatures that succeed at their save take no damage (instead of half).
Heightened (+1) The damage increases by 1d6.
