Meaning "to grip", this item is used to climb the Bloodfalls in Deadside, Temples, and the Asylum.
It's not a weapon and the moment Shadow Man finds it, he's equipped with it for the rest of the game.
When it is in use green voodoo smoke emits from it.
In 2econd Coming, there are still waterfalls of blood but they cannot be climbed.
