This tank build is built around my arcanist dd and healer build
All in all this would have the dds hit penetration and crit damage cap, while providing other strong buffs and making sure the enemies hits like a wet noodle
Skill priority goes like this:
Boss fight:
Before engagement
1. Runeguard of freedom
2. Frostcloak
In fight
1. Runic sunder
2. Elemental susceptibility
3. Elemental Blockade
4. Soul blast
5. Shield throw
