1. Ultra Mecha can evolve once at each 10th level. Each evolution requires a certain quantity of items, and requires the Mecha Factory to reach a certain level in order to complete the evolution.

 

2. Each evolution will get different evolution stats according to the quality of Ultra Mecha. The effect value of each evolutionstats will be different, and the max effect value will also increase as the quality of Ultra Mecha increases. Evolution stats and effect values are obtained randomly. If you are not satisfied with the stats or effect values, you can refresh them with reset items.

 

3. You can also lock evolution stats. A locked stat won't get its type changed (effect value may be changed) when it is refreshed. Locking one extra stat doubles the cost of reset items. For example: Locking one evolution stat costs 2 items; Locking 2 evolution stats costs 4 items; Locking 3 evolution stats costs 8 items.

 

4. If you want to replace the evolution stats of a Ultra Mecha, you can go to the Shop to purchase the Ultra Mecha Quality Retrogression item, which can Retrogress your Ultra Mecha to commom quality. All evolutionstats will be cleared, allowing you to evolve the Ultra Mecha again and re-choose evolution stats. Please note that after using the Retrogression item, the Mehca's evolution buff will be cleared and you need to re-evolve the Mecha. Please think twice before using the item.
