Royal Menagerie is hard but how you would expect in RPGs
Some people who attempt this boss and cleared it with no knowledge of the fight other than that the boss was originally a SUPER BOSS from a previous FF game basically means even the RNG of accuracy is gone now that does not mean bosses will kill you with RNG mechanics... and I welcome these kinds of fights where everyone is capped but RNG really screws them over... reminds me of D&D stories and memes... if you ask that the fight be not so you are wasting your breath...
