Purity Chest

The Purity Chest is a chest found in the War-Mode dungeon, and is only found once War Mode has begun. Whenever the player is within 10 blocks of it, it gives them the "Purified" buff. It is the only chest to give a buff. Inside of it is the Legion's Wheel. After opening it, it will continue to give the Purified buff, no matter where it is put. In addition, when placed in any contagious biomes, it will reverse the growth of the biome, causing it to shrink back. The place where the biome once was will be replaced by The Purity.
