What if we would have a glacial

and make him deal aoe on-hit damage by his other trait. https://i.imgur.com/9GfBF3U.jpg And his skills would give him attack speed and lifesteal, so he wouldnt really need items to be useful but if he get any of those traits from items too it would be overkill https://i.imgur.com/EMqLDsB.png and lets also give him debuff immunity on his skill so the only way to stop him would be to kill him, which would be impossible in the inexistent interval time you have to take even half of his hp https://i.imgur.com/bc7LMOz.jpg
