This mod adds an end game ore called corrodium where you use an upgrader to upgrade it with an expensive currency and a tool maker that turns it into tools (and armour). The better the ingots, the better the tools. Use purpur and an endrod crafted into an igniter to go to the new dimension! In this new dimension, you can find a new ore called corrodium. Using the upgrader block, you can upgrade the corrodium with crafted reinforced particles made from particle ore.
