When attempting to upgrade an item, you may encounter its destruction. Essentially, the item becomes useless.
The developer gang has learned to identify samples of items that can still be restored, and they restore items that are often found in recycling.
For pet owners (that is, for us), they offer to redeem one random item with the developer gang coupon.
Since the exchange follows the gang's rules of 1 to 1 (1 coupon = 1 item), they themselves do not know which item will be in the gang's box when exchanging the coupon. Therefore, it could be either the best sword or just a regular second-hand item.
You can obtain the developer gang coupon as a reward for activity on DEX Tongochi.
