There are no scrolls for lvl 6 and upper spells. Only a sorcerer can get them, if you have xp cap removed and get enough xp to level that high.
I got the scrolls for some higher level spells from my BGT game, I just copied their item files into my Bg:EE game. Their text was funky, I edited them with DLTCEP and set them to spell's descriptions. Spells are there, just scrolls are absent.
I then put a few those scrolls in hard to reach places in game. So my wild mage has Disintegrate in his spell book, he won't be able to cast it in BG:EE, but can try with Nahal's reckless dweomer. It was fantastic when I got Wild Surge:NO SAVE! and bamm there went the troublesome Greater Wolfwere. lol
Umm, that files are from a BG2 game I own, so if you have BG2 game you can transfer them to BG:EE easily. Or, since spell files are in BG:EE allready, you can create the scrolls you want from scratch with a game editor like DLTCEP. Look into an existing scroll for a spell, copy its effect of learning spell, create a new scroll, paste that effect you copied and just change the target spell's file name to spell you want.
I am not sure if there is an existing mod that puts high level scrolls into game for BG:EE, it would be relatively easy, infact so much easier than that HLA mod that exists. You may request a mod for this.
I have the files ofcourse, but I am away from home right now and for the weekend, probably.
