I just do not pick up the scrolls from enemies that are too dumb to be able to use them. If a mage dies and there are some scrolls, I will take em. If a troll dies and there is a 8th level scroll on him I ignore it. There is no logical reason for an ork to be carrying around delayed blast fireballs. In fact there is hardly any reason i can think oo for any "dumb" monsters like gnolls, orks, trolls, kobolds, to be carrying ANY scrolls. even identify.
In fact, there is no reason for my 5th level wild mage to be copying delayed blast fireball anyways.
I only collect and copy spells that are 1 level above the ones i can cast. So my 5th level wild mage who just learned to cast 3rd level spells is able to glance at the 4th level nagic. I see it sort of like "studying the spells" and preparing for use
thank you very much for your answer. I have another problem now. can not progress in BG2 with this setup. from the very start my character just sits in the cage in the prison in the very beginning and nothing happens
