Deaths Dance and Hextech Gunblade Healing Passive Stacks
I was playing 3v3 ranked flex as Garen and I built Deaths Dance for the 33% AOE heal, but then I wanted to heal more, and I built hextech gunblade because I noticed the passives were different and my healing increased drastically, I started trying this on Darking Kayn and realized with his passive I was literally unkillable. Pretty busted if you ask me.
