Thanks for the info.
I had little choice on the matter of leveling Azlar to 2/60 - it was either him or 2-star red heroes for me (Never got a 3* or 4* red early). In fact I got Kelile quite much later, at the time of my first Atlantis rises - from the Atlantis portal.
@Muchacho - my roster literally contains only seven 4* and one 5* total, and I already listed all of them - from those only three at 70 - namely cBoldtusk, Melendor and Cyprian, no emblems, one soon-to-be 70 - cChao (all mats present), three 2-60 (Sonya, Kelile and Azlar) and one 1-1 (Sumimoto). I don’t imagine 3* being helpful in the Epic or Legendary challenge events, correct me if I’m wrong, although I think that cIsshtak could be good if only the event didn’t reflect green. Have cValen as well - probably he could be of some use? Also is 2-60 Kelile even worth considering? Won’t she die too fast?
@Noble_Weasel - I found out about unfarmable ascension mats when I hit 2/60 with Azlar - up to that point I thought I could assemble everything needed for hero ascension from regular map battles. The moment I found out about unfarmable mats, I focused on rare quests and events which could give unfarmable ascension mats - such as the challenge event. I’ve been completing rare quests up to the last battle since the start of December (Mount Umber more precisely was my first rare quest and I got the blade but not the rings, as I said), but the reason why I wanted to complete challenge events was simply more unfarmable 3* mats upon completion on each of the stages. I’m not competing for top score or anything - that would be ridiculous for me and my poor hero roster to even consider
Also, being stuck with Azlar at 2/60 for a pretty long time, I may say with the right tactic he won me quite a lot of fights - raids and regular. Also he was the tankiest of all my heroes for quite some time since I was stuck with a team of 2/60 Melendor, 2/60 Azlar, Bane, Renfield and Valen for nearly 2 months of play.
