Compared to the original 5/5 solo, this one is much easier thanks to the extra stats from level and cake. No flinch needed as well, and you can run GMS 9 now instead of FT2 thanks to the better gauge management.
Like its other lake trio counterpart, avoid all haxes and nat crit, and use Dragon Pulse when you have enough gauge.
