Marrik: Is there any way to do it, or get a follower to do it? My tech aptitude is 60, I fails every time I try. Is there some way to make a companion use the scroll?
Followers can't use scrolls. The only scroll I've never seen fail due to high TA is the Scroll of Exiting. (And that may have been nothing more than sheer dumb luck.)
So to answer your question: your best option is save scumming.
1) Quick save (F7) right before trying.
2) Use the scroll.
3a) If it succeeds, continue.
3b) If it fails, quick load (F8) and try again.
At some point, given enough persistence, the game's internal random number generator will roll high enough.
Marrik: This is my last question for a while, I swear. Heh.
I call shenanigans. ;)
