This plugin should be compatible with all protection plugins, plugins that cancel entity damage events and block break events. It should also be compatible with a majority of third party enchantment plugins and even plugins like McMMO. Attacking with an off-hand weapon uses a modified version of Mojangs own attack code so it should react and behave exactly like a a weapon in the main hand! Tools that mine blocks are virtually the same speed as in the main hand, normal enchantments also work. 1.8 PvP plugins are also compatible. Attacking still has a cooldown but it is impossible to show the animation as it is client side.
