But if you are trying to get the jump on a warrior and blind him, do it just after he starts hitting a mob, so that whilst you are lagged from reciting, the mob is taking hits and not you (unless you happened to fail the recital or he saved vs the scroll).

My gnome voker basically killed people as follows:

Used size to avoid being lagged so easily. Cast a spell or two (exploiting vulns where poss), then recalled, healed and refreshed at healer, went back and hit the warrior again until he died. Worked more often than you might expect. Of course, it is a quite expensive process.
