Lore: These are rare, highly-prized
devices, made by some forgotten magical
means. They are fist-sized green
stones that glow when operating. They
are very brittle.

These amulets are prized highly
throughout the Forgotten Realms and
are generally found in the possession of
high-level adventurers and experienced
diplomats.

Functions: When worn next to the skin
they confer upon the wearer the protection
of a mind blank spell, as well as
immunity to: chaos, forget, geas, hold
person, hypnotism (but not hypnotic

pattern or fire charm), mass charm,
quest, scare, and sleep. The wearer also
gains a +4 saving throw against fumble,
ray of enfeeblement, and trip, and
is allowed a saving throw against both
Otto’s irresistible dance and maze spells
(if made, the durations of effect are
halved, rounding up).
These amulets may be worn by any
class of character. The protection they
give is involuntary (i.e. the wearer cannot
communicate telepathically even if
she or he so desires). Protection only
extends to 11-44 (1d4 x 11) spell levels
before the amulet is exhausted. (For
this purpose, protection against a psionic
attack drains the levels of the equivalent
spell.) The amulet only counters
the spells (and equivalent psionic
powers) listed, and is in no way affected
by other spells, such as lightning bolt.
Pending exhaustion of the amulet is
mentally evident to the wearer, and visually
evident to others; the amulet blazes
fiercely for 4 segments before slowly
fading to darkness.
The amulet recharges on its own at a
rate of 1 spell level per turn, but will not
counter spells which it lacks sufficient
power to negate—its protection is all or
nothing.
