Basics
Perform particle reconstructions to acquire 4 random abilities for a designated hero. One Polymer Crystal is required for each reconstruction.
There’ll be a preview of the abilities acquired after the reconstruction. Tap [Save] to enable the 4 existing abilities to be covered by the newly-acquired abilities.
You may also tap the [X] in the top-right corner to discard the result, or tap [Reconstruct] to discard the result and perform another reconstruction.

Free Chances Every Day
There’re many free chances to perform reconstructions every day, without consuming Polymer Crystals. Raise the level of the Hopeness Lab to get more free chances.

Categories and Qualities of Abilities
There’re five types of qualities in total. The quality will determine the specific number measuring the strength of the ability. Abilities of the same quality are the same in strength. Below are the probabilities for each quality:
Basic (White): 25%
Common (Green): 50%
Rare (Blue): 19%
Epic (Purple): 5%
Legendary (Orange): 1%

If the legendary quality has not appeared in the previous 150 reconstructions, it’s bound to appear the next time.
Abilities are categorized into ordinary and special abilities. The special ones are extremely powerful. Each hero can have no more than one special ability.
The probability for the special ability is 1%. If the special ability has not appeared in the previous 150 reconstructions, and there’s no special ability being locked, it’s bound to appear the next time.
If an epic ability or above has not appeared in the previous 29 reconstructions, the special ability for the next time is bound to be an epic ability. If a legendary ability has not appeared in the previous 149 reconstructions, the special ability for the next time is bound to be a legendary ability.

Locking
You may tap the icon or name of an ability to view more info. Tap [Lock] in the bottom-right corner of the info page to lock the ability. After being locked, the slot will remain unaffected in reconstructions and will NOT be covered by a new ability.
For every ability locked, the amount of Polymer Crystals required will double. You may lock no more than three abilities at the same time.
To unlock an ability, tap [Lock] again.
If the special ability is locked, no special ability will appear in reconstructions.

Decay Energy & Advanced Mode
Select “Advanced Mode” to perform reconstructions and there’ll be an 100% chance to have a special ability, but extra Decay Energy will be consumed in each reconstruction.
Each time an existing ability is covered by a newly-acquired ability, the Decay Energy will be returned. The higher the covered quality is, the more Decay Energy will be returned. When discarding abilities, you’ll also have a certain amount of Decay Energy back based on their qualities.
You may exchange the Legendary Hero Medal into Decay Energy by tapping the [+] next to the amount of Decay Energy. You’ll get even more with Season Hero Medals.
Free chances each day are NOT applicable to the advanced mode.

Smart Reconstructions
Select [Intelligent Reconstruction] – [Reconstruct] to perform smart reconstructions. As long as there still are enough Polymer Crystals, the reconstructions will keep proceeding on and on, till a legendary ability or a special ability of any quality appears.
The intelligent reconstruction is also applicable to the advanced mode.
