Scrolls are single use items that will cast a bound spell
when used. A creature wishing to use a scroll must know how
to read by having learned the
Literacy: Common talent.
Scrolls have a power level, or mastery modifier, that ranges
from 0 to 5 and determines how powerful the scrolls' effects are.
Regular scrolls have a mastery modifier of 0 or 1, adept's
scrolls have a mastery modifier of 2 or 3, and master's scrolls
have a mastery modifier of 4 or 5.
Some of the following scroll descriptions use X instead of
(mastery modifier or 1, whichever is higher). For example, if an
effect's duration is XD6 x 10 turns and the mastery modifier is 0,
the effect lasts for 1D6 x 10 turns.
