Chaotic Godsword

The Chaotic Godsword is easily the most powerful melee weapon in the game. It can be crafted by combining a chaotic blade and chaotic hilt, and has a very rare chance of appearing in a village blacksmith chest. The sword has infinite durability, extremely high enchantability and outputs massive damage per hit. It is around five times more powerful than a diamond sword, and is able to kill most mobs in one hit (boss mobs are notable exceptions). To compensate for its outrageous power, the sword has an equally outrageous crafting recipe. The components needed to construct a Chaotic Godsword from scratch are:
 * 3 Nether Stars
 * 6 Onyx
 * 6 Dragonstones
 * 304 Coal
 * 18 Leather
 * 20 Obsidian blocks
 * 16 Diamonds

A Chaotic Godsword inflicts 34 damage (17 hearts) per hit.
