Rod of the Dark Lady

A rod of the Dark Lady was magical rod, created by the faithful of the chromatic dragon deity Tiamat, to aid her followers in their eternal struggles against the clergy of Bahamut.

Description

Twice per day, the wielder could fire a chromatic ray at a good-aligned dragon. Once per day, they could create a shadow of the Dark Queen-like effect.

History
The first rod of the Dark Lady was created by Shudu-Ab, a high priestess of Tiamat within Unther. She saw their use in battle granted a significant advantage to the priests of Tiamat and frustrated the metallic dragons by decreasing their prowess in combat.
