Rules of Hero Synthesis

1\. It takes 3 heroes of the same quality to synthesize a new one. You will obtain a hero of higher quality if the synthesis succeeds, or one of the same quality if it fails. The success rates of Hero Synthesis are listed below.

2\. Heroes are categorized into N, R, SR, SSR, and UR in ascending order by quality.

3\. The new hero will inherit the level of the used heroes in the following manner:

If three N heroes of level 5, 6, and 7 respectively (their upgrades consumed 3,300 WNH in total) are used for a successful synthesis, the new R hero will inherit the resources used for their upgrades and be upgraded to level 10. &#x20;

4\. The synthesis fee and success rate vary depending on the quality of the heroes used. Here are the details.

| Quality of the heroes used | Success rate | Successful synthesis | Failed synthesis | Token needed | Amount of token consumed |
| -------------------------- | ------------ | -------------------- | ---------------- | ------------ | ------------------------ |
| Nx3                        | 70.00%       | Rx1                  | Nx1              | WNH          | 50000                    |
| Rx3                        | 65.00%       | SRx1                 | Rx1              | WNH          | 50000                    |
| SRx3                       | 40.00%       | SSRx1                | SRx1             | WIN          | 70000                    |
| SSRx3                      | 25.00%       | URx1                 | SSRx1            | APENFT       | 20000000                 |
