Staff of the adder

Staves of the adder were one of the many variants of staves of the serpent found throughout the Realms. This type of the enchanted staff could transform into an adder to strike the owner's enemies.

Powers
By speaking a command word, the wielder of a staff of the adder could cause its head to animate into an adder. This effect lasted for one minute, or until the wielder spoke the command word again to return it to its inanimate form. If the snake was killed while animate, the staff would be destroyed.

If used as a weapon, a staff of the adder could inflict a target with poison.

History
In the 14 century DR, staves of the adder were often used by clerics of evil deities, giving them ill repute among many.

Sometime in the same century, Reptilla Half-elven lost her hand-crafted staff of the adder in her battle with a bronze dragon whose lair in the Dragonspine Mountains she attempted to claim.
