Confirm the required materials, then select Ascend. For exp materials, farm blue ley lines. They'll help you level characters up. It'll take some time but you'll get there. If you think it's taking too long to get the entire team levelled up, just do the one or two characters that are mostly on the field first and then for convenience keep the rest a few levels lower, at most 10 levels.
