Using Psionic Powers

All psionic powers have a MAC score. To determine if a psionic power works against an open mind, a player must make an MTHAC0 roll against the power’s MAC score on 1d20. Any roll equal to or greater than the number means the power has been activated and its effects are applied for that round of play.

All powers have a cost per round of use. The cost listed to the left of the slash is the number of PSPs needed to use the power for a single round. The cost listed to the right of the slash is the number of PSPs expended if the MTHAC0 roll fails (in which case the power’s effects aren’t applied).

Powers that have been successfully activated can be maintained from round to round without making additional MTHAC0 rolls. The psionicist simply expends PSPs to pay for the power’s cost. The first round that the character fails to pay the cost (either voluntarily or because his PSPs have been depleted), the power’s effects cease to function. If the psionicist wishes to reactivate the power in a later round, even against the same target, he must make a new MTHAC0 roll. If an MTHAC0 roll to activate a psionic power fails, and the character has enough PSPs remaining, he can try to activate the power again in the next round by making another MTHAC0 roll.

A roll of 1 is always a failure and a roll of 20 is always a success, no matter what the power’s MAC or the psionicist’s MTHAC0 scores are.
