One problem I've always had with the spell is that its effects aren't enough to really pull one out of a pinch per say or even deal copious amounts of damage other abilities do. Personally I'd like to see it half casting/recast time of spells and increase stat modifiers. As for new spells at 90-99.... Make them HNM moves. It'll give more life into HNMs and their KSNM counterparts to be killed for things other then BBelt items.
