Not technically enfeebling magic, but id rather not take up another thread at this point what with rampant derails abound. Hows about a self or aoe or single target buff similar to gear buff again. Perhaps its time for a "converts damage taken to MP" buff effect, can be a small percentage, or like temper, can scale with gear/skill. I can see it potentially useful, though only some jobs would make use of it meaning no large 6 party member cycles, just whm/blm/pld/drk/rdm/blu/smn/sch, and most of those arent likely to get hit often. Just a thought.
