what are u think about this builds for hardcore? also rec some good builds for hardcore. It will be super good if your build will have enough survivability and good farm speed.

Since you're asking in the Marauder board, maybe a Flame Totem Chieftain is for you?

Here's a nice example using only four links (in Hysteria gloves) and Kaom's Heart, the build is chill/freeze immune and receives +3% to maximum resistances as well as perma Onslaught from the shield. Sounds ideal for HC.
