I like Imperil. Jynx is not really needed, though. Wound and Pain I think wouldn't really work based on the limitations of the battle engine. Veilga and Vigilga sound like they belong on WHM. Renew, on the other hand, I REALLY like. Would make RDM gameplay, specially when self-buffing for melee, easier to bear.

As far as Blitz, I like the concept, but I'd drop the whole elemental wheel aspect of it. Instead, it should build up off of itself (Eg: Inferno Blitz reduces resistance to fire-based damage). I'm iffy on the enfeeble effects attached to them, but I do like the possibility of blending enfeebling into melee. Should probably be on a 45-second timer instead of 60 seconds, IMO.
