Trap
The caster uses this spell it he expects to be mentally attacked (magical or otherwise). Once set, the trap will last for 5 rounds (ignore the normal duration of spell) or until the character is successfully struck by a magical mental attack or other form of mental probe. When this happens, the caster must make a spell rank FEAT roll. If he succeeds, the caster's stored magical Universal or Dimensional energy lashes out, causing damage to the attacker's mind that is equal to the trap's spell rank. If he fails, the attack against the caster will be successful, but apply a -2CS to the spell rank of the hostile spell.
