Rust

Usage
Most useful in PvP to make Resurrection Signet take 9 seconds to activate, but can also be effective against monks that use a lot of Blessed Signet or Signet of Devotion. It can severely disable warriors using Healing Signet, as they will take 6 seconds to cast it, and the whole time will have -40 armour.
