Well, bojack. On earlier levels, sure. Up to lvl 55, enfeebling is a terrible must. But once you start getting those reflects, it becomes tiresome. A blinda and blind spell combined cost is around 24 I think.. Which is 100 hp of a cure II.
If you go to adeewa (I love that place) enfeebling the crawlers and diremites will really save you ALOT of mp. Espc a proc on paralyze during a tp move.
