This is a small mod that adds materials from the Undergarden to Tetra. Currently, it adds depthrock, shiverstone, grongle wood, wigglewood, smogstem, cloggrum, froststeel, utherium, and (in 1.1+) forgotten metal.
Froststeel, utherium, and forgotten metal maintain their special weapon properties when made into Tetra tools using the new Tetra effects Frostbite, Rotbane, and Threnody of the Deep.
Version 1.0 is for Tetra 3.4.0+ and the Undergarden 0.3.8. Versions 1.1 and above are for Tetra 3.4.0+ and the Undergarden 0.4.0+.
