The best party is simply whoever your highest level characters are, although because Kaiser has a Heaven Affinity, any Frost or Fire characters will be taking a bit of extra damage. Di and Frieda both have an Earth Affinity, so if you have them at a decent level I recommend them, although the first time I cleared the fight I was just using Lottie, Trixie and Addie (1 Fire and 2 Frost Affinities, all weak to Heaven) The key to this fight is avoiding his insta-kill attack. Even when playing through the game a second time, he was getting 1-hit kills on a level 62 Addie with 9,000 hp. I found that once he uses this move, he'll usually spam it. Bring A LOT of Yggdrasill's Tears! 15 is more than enough, but I'd say at least 8 or 9. If he's spamming the insta-kill move whenever you try reviving one of your characters, thereby killing both of them, just wait a turn before reviving them again. He'll usually use some other move after that. There's also a skill you can buy for your protagonist which casts Rebirth from pretty far away, and I believe it costs 3 AP? He has another one for 300 Tension, but that might be a bit more difficult to build up continuously. So, in summary: •Just use your strongest team •Dont let him take out your whole team when he spams the insta-kill move •Yggdrasill's Tears are your best friend (Panaceas are important too, maybe 5 or 6 should cover it. Only use them when you have a very bad status ailment on though, like the ones that block you from using skills. Its kinda wasted if you just use it to cure the speed lowering debuff) •Your protagonist should be used for support (a lot of his skills buff your team, if you have an AP regen skill you should put it on him) And one last note, dont worry about attacking anything except Kaiser or the crystal enemies knights will spawn. The crystals will help you build Tension, and you might as well hit the knights if you are using an AoE attack (make sure you're still hitting kaiser!) Depending on what difficulty you're on, he will have roughly 50,000 hp. This sounds like a lot, but with 3 attackers and your protagonist providing support, it can go surprisingly quick. Good luck!
