From Dragon Mania Legends (DML) Wiki
Dungeon Tokens are an In-Game Currency exclusive to the Bottomless Dungeon. These tokens are used for purchasing exclusive Dungeon Shop Dragons, Decorations, and Special Offers. They are also used for purchasing and clearing certain islands.
The only way to obtain Dungeon Tokens is by opening dungeon Chests, though none are awarded if a Dragon is found inside the chest. The Dungeon resets every week; thus Tokens can be earned every day. Between 16 and 350 Dungeon Tokens are given per Dungeon Chest.
- Update 4.9: Raised the cap on Dungeon Tokens from 10,000 to 10,500.
- Update 4.6: Introduced, replaced Blue Dungeon Tokens.
