Relatively New player here (started under 30 days ago) with some questions about Assentation.
I may make a lot of you cringe with this and I'm sorry in advance if I do. How much if any have I weakened my champions by not ascending them from the start? (So for example I leveled a Kael up to 50ish before ascending him to 5 star) Stupid I know but we all were new once and made dumb mistakes, My question is, are they now basically useless for later game things like high levels of dungeons and clan boss because I ruined their stats?

And if I have ruined them, what is the proper way to ascend a champion. All at once? Once every 10 levels? Or something else?

Also does anybody know of a guide or chart for how many potions it takes for each level of ascension for each rarity? I have extra energy and want to farm XP for food while doing void keep other dungeons for a 2 for 1 return.

Thank you for your time and any help you can give.
