This is my first blind attempt for the first summer event. So I got my hands on OK's EX and immediately prep'd him to a servicable unit. And I must say, I wasn't disappointed. Even without his 35, he packs a punch in this event. A bit fair of warning though, OK will surely fall off on upcoming Cosmos stages but I'm enjoying using him. As long as I enjoy a unit, I will use them until they can't complete events anymore.
Now for the strat which I didn't actually used here:
For the first wave, focus on OK first which hits ~hard~ and ~fast~. After burning him down, CoD is pretty easy.
For the 2nd wave, Exdeath should be killed first since he can use a bunch of hp attacks. Luckily, I brought Kefka with his hp disables.
For the last waves, use Golbez and spam aoe attacks. And save melee skills for Vayne when he changes to magic mode. Aside from that kill Vaan first.
And don't use your skills at leisure. I genuinely thought I could clear waves faster since I was so used to clearing waves quickly before. The result is I lost skill count on the last wave and barely finished it with active buffs.
With all that said, thanks for watching even if there are so many videos out there already.
