Equivalent Exchange

The Equivalent Exchange mod is based around alchemy. It adds in a number of extremely powerful end-game items that require large quantities of diamond to make, and large quantities of glowstone to power. It also grants the ability to easily condense materials into more valuable forms, up to diamonds and diamond ore. Most of its recipes are based around the Philosopher's Stone, which you will need in order to access much of the new content. The "currency" of this mod is EMC the more valuable, rare and useful the more EMC an item is worth for example diamonds are worth 8,192 EMC and stone is worth 1
