DagSP

Adds 20 New Tool recipes made out of 4 new materials: Resin, Amethyst, Sea stuff and Sculk

Adds 6 Geode structures each one with a gem type you can upgrade tools/equipment (and rings!) with, lets you mix between Overworld Gems and Nether Gems so each item can have max 2 gems.

Focuses on a much harder Vanilla Survival experience. Not only by making mobs stronger or more resistant, but adding new mechanics and unique twists. Also letting you progress slightly faster (if you're skilled enough)
