Who is this Mei girl I see in couple of my friend's shared heroes and how to get her? AFAIK that should be the human girl from which Chang'e is made. I do not see her available anywhere. She is incredibly useful.
It is a skin for ChangE, can be received from Re:Birth Labyrinth. It is only a cosmetic change and has no additional benefit compared to using the default ChangE skin.
Damn I only just realised it is completely same skill set as Chang'e. Didn't looked at the skills at all before posting this.And question about Rebirth Synthesis.. Does it only resets when you get all the items, with synthesis reset ticket and crystals or does it resets after certain amount of time? I mean, it is not stated in info so I guess not but it doesn't hurt to ask.
When u acquire all item on synth board, you're given a new board and a reward when board is cleared (3-5* x10 ticket). The board stays until u clear it using relab coins or reset the board using crystals or grid ticket.
