Alter Gravity

Requirements- CL 7
Save- STR or DEX
You may increase or decrease gravitational forces within an area no greater than 5 ft per 4 CL radius. This effect lasts for a round per 3 CL.
If you decrease gravity, any creatures within the AoE must make a DEX Save to exit the area before they begin floating (treat as Rooted Status Effects, except they ARE moving, just outside their own control). Each round they are within the AoE creatures float up 10 ft higher. When the effect ends they may make a DEX save to take half fall damage (1d6 per 10 ft).
If you increase gravity, any creature within the AoE gets a STR save. If they pass their movement speed is halved until they exit the AoE. If they fail treat them as having the Rooted Status Effect, and they take 1d4 per 2 CL damage. Each round they spend within the AoE they must make a STR save, with the same consequences for success or failure.
