[2.2] Iron Maiden - Super Tanky Ranger that packs a punch

I use Static Strike + Multistrike + Weapon Elemental damage + Added Fire Damage and The Bringer of rain

Ah, with the helmet, not able to use chest armour. got it. :/

Why a ranger as tanky instead of others?
Is it due to ascendency skill?

Just as a heads-up: If you're a noob like be you might not realize that it's not easy (or I'm just super unlucky) to get these chrome rolls on Rainbowstride (and Bringer of Rain?).

It doesn't really matter though and this has been one of the most fun chars I've ever played (Volatiles only tickle a tiny bit with this build ^___^), thanks a lot!

Is this build 3.0 viable? Including gear...
