And here's the latest Arcade stage, with an updated strategy! Here, I use Rook's Gambit instead of Gouge because of Rook Counters giving green stars. After a dozen frustrated tries, I couldn't believe my eyes when I got such an incredible score!

However, I don't intend to redo the other stages for 1.20. As you can see, even with this updated Arcade Mode, the strategy remains unchanged, which is certainly disappointing. Will-o'-the-Wykes specially remains king (useful not only to protect yourself, but to always keep the Techinical Bonus up from its constant chip damage). Why they can't remake the battle technique system so it's possible to get rainbow stars with every ability is something I don't understand.

Finally, let's talk a bit about accessories. The Grace of the Inferno is simply too important, so discarding it is NOT an option. As for the new Bit accessories, there is a clear ranking for me:
1) Revivement Bit (a MUST, nuff said. It has everything: +50% LB Regen, +25% LB Ability damage bonus and Auto LB. This is also why, from now on, you never go below the last LB bar!)
2) Escapement Bit (very useful for the cooldowns, not so much for the HP)
3) Bombardment Bit (the combo potential it gives is just night & day. Was sad to sacrifice it for The Grace of The Inferno)
4) Disengagement Bit (kind of trash, it only shows when you should have parried)
5) Assailment Bit (a single Rainbow star for reaching 2x stagger is NOT worth it even if you factor out the fact that increasing damage output is not good for Arcade).
6) Nourishment Bit (somewhat good by itself, but completely redundant when Revivement Bit is a thing)
