Staff with clicky effect...Does anyone remember?

[Messianic]

When I played a wizard on live, there was a clicky staff that only needed to be in your inventory to use. The effect was instant, and it slightly reduced the target's elemental resistances. The most important use of this staff was it allowed me to insta-pull something without stopping, making it critical for quad-kiting.

Does anyone remember what it's called or if its present on p1999?
