In reference to Ghen's ink making process on Riven, and to provide a use for the beetle carapace from the Mystic World mod, I've created this useful script. 

This script replaces the "dyeBlack" used in Mystcraft's ink vial recipe with the "carapace" item that can drop from Mystic World's beetles. This serves two purposes: 1) as thematic flavour, and 2) to make the ink a little more difficult to acquire.
