Powers and psi-like effects targeted on you are reversed back upon the original manifester. Reddopsi turns only powers that have you as a target. Effect and area powers are not affected. Reddopsi also fails to stop touch range powers. Up to 15 power points (or eight spell levels in psionic-magic transparency games) worth of powers are reversed in this fashion. When you are targeted by a power using a higher amount of power points than the amount of reddopsi you have left, that power is partially reversed. Subtract the amount of reddopsi left from the power points of the incoming power, then divide the result by the total power points of the incoming power to see what fraction of the effect gets through. For damaging powers, you and the manifester each take a fraction of the damage. For nondamaging powers, each of you has a proportional chance to be the one who is affected. If you and a manifesting attacker are both warded by reddopsi effects in operation, a resonating field is created.
Roll randomly to determine the result.
01–70 Power drains away without effect.
71–80 Power affects both of you equally at full effect.
81–97 Both reversing effects are rendered nonfunctional for 1d4 minutes.
98–100 Both of you go through a rift into another plane.
