When you have magic scrolls or potions that you just wish could be used loads of times check this cheat out.
Repeatedly throw the item against a wall (or just send a fireball at it if you're impatient) until it turns in
a pile of debris. It would seem to be a waste but when you pick it up you'll find out that you could use it
loads of times and as far as I know it'll stay forever.
Get one of heal, fly, restore mana, light, smite foe and you're nearly invincible. Now the only problem is sorting
them out.
