This spell is a Plane of Air drop yet it is 100% obsolete to a 150 point LDoN spell (possibly 300 dont recall right now). True Death has 90 mana regen at the cost of 90 health, where Darkest Possession has 90 mana regen at the cost of 65 health. The only advantage True Death has is that it gains water breathing and werewolf illusion, of which id rather be a Skeleton or a Lich even (you know, something more necromancer like and less enchanter?). The water breathing is obviously obsolete due to the fact that almost everyone has a faerune helmet which grants water breathing permanently.
My proposal is to change true death to Lich illusion, 90mana/45health or preferably 120mana/65 health as the health portion is mildly irrelavent due to regen spells/gear it would be better to gain mana regeneration on it instead of another health reduction. Also to put it at the same health conversation as Darkest Possession would be good. Also bumping the duration to 1 hour like Darkest Possession couldn't hurt either. Obviously numbers can vary on what you see fit, however they do need to change imo.
