Gemling LegionnaireWelcome back, Filthy Exiles!
This is my 0.5.5 Icefang Poison Shield Wall Gemling Legionnaire, built around turning Shield Wall into a tanky poison-based league starter that can progress all the way from the campaign into endgame.
The core of the build is 
Shield Wall + 
Resonating Shield, allowing us to scale our shield defensively while also using it as our primary source of damage. Shield Wall delivers the heavy hits while our Poison, Bleed and Plague mechanics add strong damage over time and help clean up packs. We switch between blowing our Shield Wall up with 
Fortifying Cry and 
Infernal Cry with an aim to hit 3 stacks of poison so we do maximum overlapping damage.
Icefang Orbit becomes a major part of the endgame setup, giving the build its Cold/Poison identity and adding another layer to our ailment-based damage.
Defensively, we combine strong shield defenses with Armour, Evasion, Block and additional defensive layers rather than building a glass cannon.
The Gemling Legionnaire is a great fit because of the flexibility it gives us with attributes, skill gems and overall character scaling. This lets the build transition smoothly from a relatively straightforward campaign setup into a much more complete endgame character.
For clearing, use Shield Wall and Resonating Shield to tear through packs while 
Herald of Blood and 
Herald of Plague help spread the carnage. Against bosses and tougher rares, get your Shield Walls down, use your Warcries and maintain your Poison pressure.
NOTE: This build can 100% be pushed way further!
