Spell Scroll

This bears the words of a single spell, written in
a mystical cipher. If the spell is of a higher level
than you can normally cast, make an ability check
using your spellcasting ability to cast it. The DC
equals 10 + spell's level. On a failed check, the
spell disappears the scroll with no effect.
