Gulg's Gurdle

Gulg's Gurdle [sic] is an armor piece added by Witchery. It provides armor points at 226 durability. When worn in the leggings slot, it will allow the player to launch entities up to 10 blocks by punching them with an empty hand. This is high enough for them to be afflicted by fall damage. It will also increase the player's punch damage up to points, rather than the default. Wearing the Gurdle while near a player that is wearing Mog's Quiver will give the Gurdle wearer resistance effects.

It can be obtained by slaying Gulg.
