Dungeon Token

Dungeon Tokens as they appear in the players Inventory. They ARE Stackable.

The Dungeon Token
Dungeon Tokens are the primary and only currency for special rewards. They can only be obtained from the Arkhan Megadungeon by defeating its endless trial of bosses and floors.

On a similar note, Dungeon Tokens can, in fact, be stacked AND compressed into a smaller unit to stack: The Dungeon Medallion. When one has 100 Tokens, they may exhange them for a Medallion to help save space in ones bank or inventory.

Trading a Token
While farmable by a player, they may only get about 3 tokens every 20 minutes. However, for players that may be in dire need of these tokens, they are worth trading for.

A single token, even though it is of Golden rarity, is liable to be traded for items of Green, Yellow or Orange rarity. Entire stacks could be used as leverage for even better items.

The Dungeon Shop
As said, a Tokens only value is for this shop. Items of various rarities may be bought here; Armors, Weapons, Potions and crafting items alike. Be warned, however, as there are no refunds.

Trivia

 * Some items in the Dungeon Shop can only be found, and bought, there.
 * The Legendary, Starfury, can be bought with Dungeon Tokens.  It's also an extremely rare drop in the lowest floors of the MegaDungeon.
