I have a 3* Doc Ock at max champ level (266), and a second at max level (166) waiting to be promoted. The character doesn't appear in the ascending menu.
Not sure what I've done wrong?
3* Doc Ock is not yet eligible to be ascended.
There's a table here with a list of the characters you can ascend:https://forums.d3go.com/discussion/89125/new-feature-champions-2-0-live-with-r287/
Well that'll do it. This kind of puts me in a pickle. I'd like to promote the other one for the rewards, but I risk locking myself out of ascending later should he be added to the roster.
You won't lose rewards, if you ascend by binding to a championed character, you get credit for the extra covers you applied to the second character.
