I'll try getting the crystal ring shield as well. The old close range tactic doesn't seem to work vs the Four Kings in NG+ so I might try ranged battle next time. Even with teh iron flesh I still take massive damage when they use their explosion and projectile attacks. I found it easier to hurl fire orbs at them but I've only got 12 orbs, just enough to beat one. Summoning players and the witch didn't help much(meron pa yung isang player hindi/ ayaw tumalon sa abyss
