Masochism set in Codex have in description that it increases healing/hp, and when above 50% hp healing damages you. When you look at the physical item description, the thing that is correct is that healing damages you but instead of hp/healing buff you see damage buff. Didn’t test how the item works if it buff hp/healing or damage.
The hammer on screen is crystal legend drop from long time ago, i don’t even remember what legend that was. Then i removed everything from it, only block chance left. Added crystals that gives sockets and crafted earthquake. Maybe it depends when item was dropped not created? If so, sorry for problems ;c
Item on screen may be warrior Crystal Gelid Smasher becouse it have epic block, and this one have crystal block. I also had equipped warrior Insolence with nova mythic. while crafting this hammers earthquake. But im sure i crafted it after patch 2.2
