This is the last Dungeon in your adventure, and the most dangerous one yet!
Venture through an Elemental themed Dungeon with a team to defeat Elemental themed mobs and bosses, and finally, the Fire Champion to earn rewards such as Crate Keys, Custom Enchants, Mob Coins etc.
Purchasing this item grants you an Elemental Dungeon Key, which can be used at the Dungeons NPC at spawn. Better to have a team to successfully complete a Dungeon!
