Staff of divergence

A staff of divergence was a magical staff that defended the wielder against a specific type of attack, such as fire or lightning, that was designated upon its creation. Any attack or spell of this type cast within 9' (2.7 m) of the staff was automatically turned away to a location up to 90' (27.4 m) away. Additionally, the staff could, at will, emit a faerie fire–like radiance of any color.
