As a cure potency received spell, I also agree that isn't going to help Rdm, as Cid remarks it's just a bandaid that doesn't fix the core problem (with healing). In terms of enhancing, Rdm has highest base skill, but any mage can equal that with /Sch arts, and has enough gear to either match Rdm or get fairly high enough.

I'm with GG, I'd prefer a new method of debilitating the mob that isn't going to be resisted by anything since CoP. As for a DT esque spell, I'd only agree if it isn't applied to cap (call that broken if you wish, but not breaking the cap is one of the reasons I find M Torment's aftermath pretty lackluster). BTusk has issues with cast time set points and duration, not to mention not stacking with Phalanx.
