Non-event AP use?

I always have servants I want to level, so embers never go out of style. I don't do just a team or two, and am building with lots of diversity in mind.

Mostly embers and QP for me. Sometimes when I have new servants or old ones I can get to 4th ascension I try to do their interludes/rank-ups during event downtime. Other than that there's not really anything you can do.

QP farming. You can never have too much QP.

Pretty much like what Zhiroc said, the 1/2 AP for ember is the right way to go right now. Because you never know whether you need more exp cards, and the last thing you want is to spend more AP to get exp when you most need them. Pretty much like everyone else, I tend to expand my team when I could so I get 1 ST and 1 AOE for each class.

Getting embers and QP. Mats droprate is awful, so I just wait till events unless I just need a few mats.

Whatever's on 1/2 AP. Rn Levelling the 1-3 stars I have as long as they don't need mats I'm saving for my gold servants (proofs are a big hurdle). It might be useful for when they have event bonuses in the future.

If there's no 1/2 AP, probably dailies and mat farming. You could farm the 15AP for silvers and burn them for MP.

Between the xmas lotteries and Salomon, I think I have enough QP till Nerofest. Cuckoo's nest is a nice CE for the ember gathering quests.

Like me I’m gonna farm Babylonia to get mats for my Quetz skills when I have the chance

QP first and Embers second. I never farm ascension and skill mats UNLESS I only need a few like say 2 or 3 more. But if anything is 1/2 AP I go for that first. If free quests are 1/2 AP then I go bond and mat farming.

All of my servants are on max level and I don't need to farm QP or MP atm, so I farm bond points for free SQ and bond CEs
