Glitches - Money from scrolls
This has been tried in Arindale, the Warrior's Guild. (if it works other places is not known)
Scrolls of Summon Undead was used. (others might also work)
If you have more than 1 scroll, sell them one at a time and the amount of scrolls will stay the same, meaning you're not loosing any scrolls. Repeat this move to get more money.
Glitch worked with v.1.0
