Don't get psyched out by a label tbh. Zeus may be mythical only, but as far as mythicals go he's not very bad at all. The first few floors are simple if you can do consistently high damage. The fourth floor is pretty much on par with biweeklies that make you fight two chimeras in that they have a good chunk of HP and hit like a truck, but if you can burst them both down you should be okay. Zeus himself should be the only really hard part.
I haven't done Zeus yet but that's mainly because I've never taken the chance.
Zeus is pretty annoying tbh, especially early on. It's just that instead of actively hosing teams, he just puts out a ton of damage. The thing that makes him relatively easy is that you can take 35-cooldown actives and it'll be okay because you can stall on the masks. The chimeras are a pain in the ass. They like to spawn on synched timers, and if you don't oneshot them you're looking at 30k to the face. Zeus is pretty beefy too. He's like about 3-4 mil health and the moment he starts attacking he'll probably oneshot you.
I did Zeus and I ended up using a stone on the Chimera. They spawned with 1 timers, I killed one, and the other was <75, so I got oneshot with double strike. I was able to handle zeus, thanks to Kirin actives and Echidna.
I...don't really have a strong blue set, at all. They're mostly all scattered and not too row focused. I could actually kinda make a blue healer, ironically. It'd just be super redundant and very weak though. Like..Gabriel/Gabriel/Ruka/Valk with I&I leaders.
If I was gonna build U&Y, I'd probably do straight up prong madness.
There's no point in going healer without an actual healer enhance- and most healers can't take advantage of PRONG MADNESS. LKali opens this up, but otherwise yeah.
U&Y would probably be more U&Y/Athena/Genbu/Finn/Arthur/U&Y. Four orb changes and two redundant cards makes it -super inefficient-, but everything has a prong and it'll bash some heads in no matter what color gets the prong proc.
Optimally, Genbu would be swapped for GZL for an attacker boost that makes all the subs hit for 50x before prongs.
The colors are scattered though. So the two-prongs won't be doing as much, and you won't have that much RCV, which could be an issue since with 4 skill boosts, you're probably going to have to stall for your actives. I don't think you're blue set is too bad though. You still have Merlin for more 2-prong fun too.
Terribly. I'm too soft.
Realistically- You should delete anyone you absolutely can not use, than trim leaders you don't use often, then just look up 297s of your favorite leader.
Pretty much this, though tbh. It's hard to tell who has what since that added that dual friend thing. I don't want to delete a Sonia only to find out he was also using a +297 Kirin/Satan/Parvati/Hermes/whatever else I actually use, so I just keep everyone unless they haven't played in like 20+ days. If they could fix that it could be great.
