Ground Control (3.5e Power)

The ground trembles and shakes.

At the beginning of each character's turn, if that character is standing on affected ground, that character must make a Reflex save or fall prone.

Augment:
 * You can spend 3 power points to make it so that each character or object that ends its turn prone on the affected ground takes 1d6 points of bludgeoning damage per manifester level.
 * You can spend 5 power points to increase the duration of Ground Control from Concentration to 1 hour/level.
 * You can spend 2 power points to increase the range of Ground Control to Medium, 5 points to increase it to Long, or 10 points to increase it to 1 mile per manifester level.
 * You can spend any number of additional power points to double the affected region for every 2 points spent. This does not follow D&D's multiplication rule.
 * You can spend 5 power points to gain the ability to raise or lower the affected region by 10 feet at the beginning of your turn.
 * You can spend 1 power point to make the affected region into difficult terrain.

For every 2 points you spend augmenting Ground Control, the save DC increases by 1.
