So I’m enjoy the game the grind can be hard be rewarding getting better at the fighting the npcs feels good, example from cheesing the B rank kill a leader to being able to solo just about the entire room is fun, and so I thought getting to my clone Bankai would be similar to that but oh helll nahhh
1st shoho can spawn a clone every 5 seconds even while he still has clones up
2nd the clone Ai is a lot more aggressive than the AI for the storm guards and i get it’s a boss can Geesh can’t get any parries off without getting hit by the other two attacks (and when I make it to Bankai mode, at least 4 people)
I get u can use ur owe clones and managed to get the first phase so I have my Bankai and ultimate, but this feels broken.

So my question is…. Is the clone Bankai broken using moves the way it isn’t supposed to and is it suppose to be this hard? When I beat it the first time I went full vitality but I was around lvl 90-110 and it took me like forever
Advice how to beat it ? I
