I did nothing but spam Yugiris and cycled through their ATK buffs, but I suppose any decent poppet will do. Then it's just a matter of moving out of AoE and putting at least one minion in the towers before they detonate.

They manage to destroy everyone even with a minion in them.

I think sometimes it happens. In my clear video I put a minion in a tower, it takes the damage and survives, yet the tower still does the aoe. It might be a random glitch.

Had fun doing the 24 challenges, haven't had a single problem with any of em. Wiped once on the nutkin one(13?14?) and the odin one. Liked all the battles and even how they introduced the battle mechanics of bosses in em.

Hope they add more later on!

There's 2 different, similar looking attacks. Early on he just uses an AoE attack that will kill just about everyone inside it, so move out. Then he adds the tower attack, which will only damage anyone inside it, unless nobody is inside it, then it destroys everyone. The fight requires constant micromanaging. You can't swarm him, or else he will run to the next arcana stone. Just attack with 4 Cid/Gentlemen at a time, and have some more on reserve.
