I jumped straight into this after completing Difficulty 5. In general, you can definitely feel the enemies hitting harder on Difficulty 10. While I could comfortably run Balloon Party with Yenisei's Ult on lower difficulties, I had to go with assist Tooth Fairy just for the stronger heals.
Assist Tooth Fairy + Voyager is the main reason why I stuck with the default load out (because it gives you assist Incantations on fixed turns). Slot 1 and 3 will spawn their assist Incantations on odd turns, and Slot 2 and 4 will spawn their assist Incantations on even turns. I can always set up Voyager's Counter/Sturdiness buff and Tooth Fairy's burst heal on alternating turns, which helps with survivability. Another thing I used more on this difficulty were the Medication equips. You can only use them once per fight, but very useful early in the run, when you're still cobbling together equips and haven't figured out the OP, run-winning build.
Speaking of OP builds, I ended up using an Electrocution / Dynamo build. TBH the strategy didn't really come together until late into the run, when I managed to pick up the Electrocution gun. Before that, it was mostly just stalling to build up Level 2/3 Incantations or acting to get Ceremonious stacks so that my Ults could nuke away enemies. Once I got Electrocution, I clean up a lot of encounters in 2-3 turns.
Despite being good at clearing out fodder, the build isn't as strong vs single boss enemies. Like, you can see that the damage vs Razor himself isn't that big. If there wasn't the mechanic where Razor loses HP when you kill his goons, I don't think I would have won this (definitely not after losing Charlie). The Charlie KO here was actually my first time losing a character in this mode.
Other random notes:
-La Source's Ult is pretty underrated. Yeah, Bkorn's Ult can probably do more damage, but you can run into enemies that develop immunity to the CC effects. The -5 Moxie effect on La Source's Ult will always work though.
-I should have probably swapped out assist Isolde for somebody else. I was kinda hoping I'd get a good FUA/Burn build like the other run. That didn't end up happening.
If you just want the Achievements, Difficulty 10 seems like the max difficulty. There doesn't seem to be any achievement for going higher. The other achievements also seem like they can be completed just on the lower difficulties.
Overall this is a very fun mode to do while waiting for the 1.9 Raids. I've already claimed all the rewards, though I'm still grinding out the other achievements.
