Rhino can become invincible and dont be affect by anything19.5sec/25 with Iron skin, 30% power duration and 4 energy atifact.

Rhino is most tanky because he can regen shield during Iron skin. I have 1000 shield so that give that:

1000 shield --> 0? Sentinel restaure my shield!

1000 shield --> 0? Iron skin!

~19sec later again 1000 shield and Sentienl's Gardian up to retstart.

But Frost is good to, he go faster and you dont need really need Iron skin if you're not a swordman.
