Control Water Pressure

Force Power: Control Water Pressure
Alter Difficulty: Moderate
Required Powers: Telekinesis
Effect: This allows a Jedi to alter the water pressure around the target, either doubling it or decreasing it by half by compressing or reducing the concentration of water molecules around the target, respectively. This power will only work if the target is completely submerged in water; otherwise, it will automatically fail.

Decreasing the pressure around an object will have no effect on the target. However, increasing the pressure could result in inflicting damage on the object. The GM must make a Strength roll to determine if the object suffers damage from the sudden increase in water pressure.

When used against living targets, the change in pressure could do one of two things. If the change is an increase in pressure, it could inflict crushing damage. If the change is a decrease, then the target could suffer sudden decompression and the bends. The GM must first determine what range of water pressure the target can tolerate. If the increase or decrease falls within this range, then the target suffers no damage. If the change goes beyond this range, then the target must make an opposed Strength or stamina roll to resist damage. Failure results in the target sustaining alter die damage, and the Jedi using this power receives a Dark Side Point.

The change in water pressure also has an affect on the trajectory of a missile or a swing. In GM terms, if this power is successful, the Jedi receives a +5 circumstantial bonus to his dodge, melee parry, submersible operation, or swimming roll. The Jedi must decide which one he wishes to use before using this power.

The area of affect is two meters, and the Jedi can choose any location as the center. The Jedi can choose to extend the area of effect, but the difficulty increases accordingly.
