Well the most unique one I built was a barb using a sacred armor stone with like 2.4k defense Non-eth. Wolf howl helm and beast with a spirit shield to add as much plus to the shape shifting skills, max iron skin, max BO, max shout, max whatever weapon mastery your going to use, and get warcry that losers enemy defense for any attack rating problems, and I had a 2 handed eth death decapitator on switch, I also tested a fortitude sword, with fortitude armor and a storm shield. Had like 6.5k life in werewolf form and 45k defense and you dony use any combat skills so you can just be super tanky with a might merc with pride, or a act 1 merc with mist or faith is fun. Alternative is just use the beast n stormshield , with might aura pride merc and fortitude armor on, with a raven frost, and a wisp projector and hot spurs or infernal strides for tons of res and absorb. You can keep a diff helm in cube and swap it out after you transform. Sorry for the run on sentences and bad structure I'm on my break at work lol
