I was at a higher level than usual for the crypts and then I met a eternal bone giant...nothing I couldn't handle until after having a 5 min battle with this guy I checked his stats.
If he doesn't look that bad, let me put it this way. I can do 1000+ damage at best on that character the best I could do with that one giant was 100. Constant damage was in 5's and 10's and he had barrier and healing, plus doing a load of stunning and applying his TW debuffs on me. I even had a 20% resist pen and it still wasn't touching this guy.
Sadly, I won't be able to fight it again when I could try to come back with a lot more resist pen due to that character clearing dreadfall and then being rolledback due to a crash and then one shot killed by a rare. (and maybe other monsters in the area)
