The psionicist converts PSPs into pure energy that resembles (but is not) lightning. The conversion is 1 PSP for 1d3 points of damage. A psionicist may convert 1 PSP per level in a round. So a level 15 psionicist may convert 15 PSPs to 15d3 points of damage. No saving throw is allowed, and powers like Energy Containment have no effect in blocking this attack. Also, spells such as Protection from Lightning and Resist Fire, are useless. If a telepathic defense mode is active, however, then damage is reduced by 10% since this energy is mental in origin. Further, if a mind is open to contact then the victim takes 10% more damage than what is specified in the die rolls. A victim takes normal damage either when they are a mind closed to contact not using a defense mode, or when they are a mind open to contact that is resisting in the manner described in the entry for the contact power in CPH.
This power is physically taxing, and may not be used for more than 4 rounds before the psionicist has to rest for 2 rounds. The psionicist may opt to expend fewer PSPs than his/her maximum. The psionicist must announce both before making an initiative roll and making a power check how many PSPs they intend to expend.
