Opal
Opaque, smooth gems, opals are pale blue with
green and gold mottling. They are related in type to fire
and black opals, but are only slightly more common. Opals
are used in a number of magic items and spells, including
helms of brilliance.An opal included in any wand with an enchantment
(charm) spell increases the save DC against the wand’s
effect by +1. If no saving throw applies or is allowed, it instead
adds +1 to the effective caster level of the effect.
