Scrolls

Scrolls perform magic when you use them. After one use they disappear.

Mixing Scrolls
With the right potions and fountains, you can easily obtain 32 out of the 40 spells with any other scroll. Arcane Scrolls can only be mixed from Change Potions.

Note that like other items, dropping a scroll into a fountain has the same effect as mixing it with a potion of the appropriate type. Thus dropping a scroll into a fountain of energy increases its spell level by 1.
