[KMS] [1.2.140] Dojo Revamp

I'm still seeing Demon slayers having an easy time with the new Dojo.
Doesnt rely on MP, check.
Has a decent drain skill, check.
Lotsa HP, check.
Lotsa def, check.
Decent damage, check.

This.

Do also remember that they get a form of Achilles so, even after a 1/1, they're likely to have enough HP left to take a hit or two as they get enough Demon Force to use a HP-restoring skill.

Also, with maxed Willpower, they'd be completely immune to status effects so now worries about getting locked/seduced.

Didn't they added MP potions? And the sauna still heals MP without giving extra seconds, so it's possible. Correct me if I'm wrong, but I'm pretty sure one can.

No, they didn't add MP potions.
Even if they had, I don't believe rest stages come after every boss which means you're still tasked with taking off hundreds of HP with a single pool of MP.

Now, would you mind answering my question?
A 30,000 HP puppet saves him seconds for what, exactly?
