The Spirit Wrackspell was acquired and used by Kain during the events of Blood Omen: Legacy of Kain in the late stages of the game. It was found by him inside a cave right after leaving Avernus, just outside of Willendorf. Could be considered an upgraded version of the Control Mind spell, because it allowed Kain to fire a magical projectile that replaced any creature's Soul with his own, taking full control of his victim's body. Like the Control Mind spell, while his soul was absent, Kain's body would be fully protected by a Repel-like barrier; and if he decided to release his grip from the possessed body or it sustained enough damage, that body would inevitably perish.
This spell is useless against bosses and like many other spells, it is only explicitly used in Blood Omen.
Though neither Control Mind or Spirit Wrack made further appearances in the series, the legacy of having a spell to control another's minds or bodies has continued - It would have been seen in the original version of Soul Reaver as the Possess ability gained from the Priestess. (a 'leftover' part of this ability was also available in Soul Reaver 2 ). Blood Omen 2 also had a similar 'Dark Gift' called 'Charm '. All of these abilities are activated by firing a projectile at the enemy to be taken over. Legacy of Kain: Defiance features the last of these abilities whereby Raziel is able to possess corpses to manifest in the Material Realm.A further mind control ability which caused damage called Dominate Mind would be seen in use by the ZephonimDeceivers in Nosgoth.
It is possible that the planned, but deleted 'Mind fragment' of the Balance Emblem, originally meant to be in Defiance would have meant access to a similar mind control spell.[1]
