Hey Guys!
I'm sure you saw the in-game announcement of Buster Call raid incoming to Global Sunday/Monday! We're nearing the end of my Japan knowledge. I think I've been through Nightmare Luffy, Raid Kuma, and then right at Boa 60 is about when I stopped playing Japan. Maybe I'll pick it up again to make sure to stay on top of things for this wiki!
What you need to know is this isn't the usual 5 turn raid level.. BUT, it's not too bad! It's easier than all 60s, Duvall, and Heracles'un in my opinion. What can be taxing is that it is long, so farming it is really annoying. The main guy you want is Momonga who is a 2.5x lead for Cerebral units AND is an attack booster for Cerebral. Woot! As usual there are turtles to stall on so high cooldown units can definitely be considered since there's so many turns and fodder/evolvers.
There are 8 stages and there being 6 bosses that you'll battle that are surrounded by minions. I can't remember if they all respawn, but for some reason I remember at least some of the levels would respawn the minion units? I guess we'll see soon, but each stage has a trick that isn't too difficult. Most of the guys do something under 20% so you'll want to make sure if you're going to attack units, you take them out.
As for your team you can do this with Slashers, Rayleigh, G3 etc. I think most legends will work but haven't tried with all of them. They each have issues. So with G3, having to hit your perfects with the number of dudes you're going to have to kill can potentially cause issues with an occasional miss. Slashers have a stage that reduce the damage of slashers by a fixed percentage. It's HIGHLY recommended you use the coffin boat if you're going the slasher route. I found Usopp and a healer are useful for whatever team you create! The name of the game is longevity and flexibility. There are a lot of battles so you can't blow your special load on every stage. Good luck with your farming guys!
