Black Opal
Black opal is a greenish type of opal with
black mottling and gold flecks, usually found in ancient hot
springs or their dry remnants. The Faerûn phrase “black as
a black opal” means, effectively, not very black (or evil) at
all. It is used to describe good-hearted rogues and similar individuals
who would be embarrassed by praise.
A black opal included in any wand with a spell that
has the force descriptor 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.
