The 'Proof of the Extreme Strong' and 'Proof of the Strong' tokens, which can be obtained by playing 'Proof of the Strong' in Closed Dungeons, will be removed this May. After they are removed, any remaining tokens will be converted into gold, so it is recommended to use them in the shop to purchase items beforehand.

Tokens obtained from Closed Dungeons can be used to purchase Artifact Enhancement Chips, Artifact Refinement Stones, Artifact Boxes, and gold. The shop resets every Monday, and you can continue to play 'Proof of the Strong' until the May update, so be sure to stock up on as many Refinement Stones and Enhancement Chips as possible.

Meanwhile, the 'Proof of the Absolute Strong' obtained from the Workshop of Radiance will remain after the update, and you will still be able to acquire more. Currently, items available for purchase with the 'Proof of the Absolute Strong' include the 'Monarch' title, the Gold Baltayr Card, and the Core Selection Box; these tokens will remain usable until further notice.
