thanks for all of the positive responses the light and dark fusion magic is just a wet dream of mine, by basically sc'ing with them, you would create cosmic elucidation, which is the SC used by tenzen, and likely can only be produced by using all SC elements in one SC, which is not possible with our current weapon skills. and yes, id totaly dig an ultima schemea, it would be freaking awesome to have some neutral elemental damage in the hands of a caster finally. as to the cure potency topic, you should include " we have 22% from the shuryas staff" which means we only really have 23% curepotency in gear outside of one overpowered TOM staff >_>!
also good point on immanence, the SC window is fairly short and almost imposible to use a T5 spell to close it w/o fast cast stratagems.
