Clerics and Paladins have the ability to turn undead creatures. When this mode is activated and the undead creatures are in range of the character, there is a possibility the undead, if they are of equal or lower Hit Dice (monster level) than the Turn Undead level, will stop attacking their targets and run away from the character until the effect is worn off.

If the Turn Undead level of a good or neutral aligned character is sufficiently higher than the HD of the undead (about 7 levels or greater), this mode will instead destroy it instantly while evil characters will bring it under their control.

While the mode is active, the character using it can't perform any actions aside from moving.
