Ancient Mixed Golems defense buff?

I thought this was common knowledge for anyone who trained here.

Well, first time I've had a 190+ character with enough HP to actually train there. My Hayato has about 3k more HP than the damage they do, and was dying even with autopot.

Still dunno if I will long term; it doesn't have anywhere I can afk reliably and I do die in about 3 hits, so it's hard to chat. (tried the top left under advice and was getting hit all the way to the edge)
