Tons of life, Tons of regen, Tons of damage, Tons of resists. Decent armor with grace, some block because of shield + Tempest Shield. Easy Atziri kills. Can be expensive (Kaom's heart), but can still be made to work with inexpensive gear.
A pretty cheap and effeicient spec. Gonna luv it ;)
Resolute Technique, Iron Reflexes.
Tankiest build ever, relying on max block, armor and a lot of life.
