Ok so new boss with my claw ninja round 2 went as follows.
I used 25k hp set and replaced my main pot shortcut from dango to onigiri.
I used dragon's claw 2,iron arm last up,sieger plate and catura.
I started at 9 clone and actually it took a while to drop to 3 and though my dps was low it was going ok.
I kept my pet skill eva buff active, makibishi active and used cephalopod ink to blind the boss.
I was chipping away and once I got below 3 clones I added bushin spam and hp pot spam into the mix.
I got cocky and decided to switch to evil dog gloves to speed things up.
That's when his mp drain got me it's also when I realised I didn't have mp pot shortcutted anywhere...died.
Pet revived but I died before I could get my act together.
I towned and ran back and continued with same tactic only I switched claws and used Hcb up for its drain (as losin dragon's claws)
He continuously drained Mp so I was spamming mp pot just managing to use skill such as bunshin before it deleted etc.
Was able to finish in time.
I wouldn't say he was hard but different I guess.
I think I needed the hp but tbh he generally didn't get my clones past 2 but I think he had a few tricks and I know dropping ho to clone above 3 is a big no go. I guess he has a smallish absolute hit and an hp based atk but I not good at telling I just stand toe to toe and quite literally claw my way through it.
