How about an Enfeebling Magic thread?

It would pretty awesome if this were a native effect of Addle, actually.

Honestly I was thinking that Red Mages wanted this spell to somehow be special for them and this is how they could have that, and that mobs casting the spell will be a pain in the butt if Addle had this natively. Still, I can see where a five minute ability would make this a pain to the point of wanting it natively.
