Black Sapphire
Black sapphire is a rare variety of
sapphire that is a deep, rich black with yellow or white
highlights. These jewels come mostly from the South,
in particular the Great Rift, since they are most plentiful
in the Deep Realm of the dwarves and are
brought up through the Great Rift to the surface
world for trading.
A black sapphire included in any wand with a spell that
has the darkness descriptor increases the save DC against
the wand’s effect by +2. If no saving throw applies or is
allowed, it instead adds +2 to the effective caster level of
the effect.
Material Cost: 5,000 gp.
