Earthbind: At-will, std, ranged, concentration; subject's personal gravity increases dramatically. Walking creatures must pass a Strength save to move, and even on success, only move at half speed. Flying creatures plummet, but their flying ability allows them to limit falling speed to avoid falling damage. Still, they cannot fly under this effect. Larger creatures enjoy no protection from this spell, as their superior strength is countered by their increased mass. Creatures who are prone under the effects of this spell cannot rise as a move action; they must use a standard action, and must pass a Strength save to succeed.

Rank 2
Subjective Gravity: At-will, swift, concentration; you change your personal relationship with gravity, in such a manner that you can walk on walls and ceilings as if they were floors. Objects that leave your person resume their natural relationship with gravity.
Rank 3
Control Gravity: At-will, std, ranged, circle 3 (height 30 ft), concentration; you control gravity in the area. Each round, as a free action, choose one:
Crush: When switching to this mode, all creatures and objects suffer the effect of Earthbind. Any non-landed creatures and objects first fall to the ground, suffering double the appropriate falling damage.
Zero G: Gravity is nullified. Walking creatures quickly lose footing and start to levitate (effectively rooted). Flying creatures can move normally after brief confusion.
Reverse: Gravity reverses, causing everything not nailed down to quickly rise to the top of the effect. If no obstructions exist at or below the max height, objects and creatures levitate at the top of the effect. If obstructions exist, they suffer falling damage as appropriate.
