DK w/ Bastion, Reinforced, 3x Bracing glyphs, Glyph of Hardening (front bar, Crusher on back), Hardened Armor, Igneous Shield, Ferocious Leap, Bone Shield, Defensive Stance (slotted, but I guess you can use it too), Tri-Focus for shield on Ice Heavy attack. Use Brands of Imperium for shields to yourself and nearby allies, can pair with Hatchling's or Para Bellum if you really want. Power Slam as a spammable for up to 50% increased damage and Void Bash to pull in all enemies around you when you do so, Shielded Assault to get around. Recommend using Redguard to make the most use out of their 8% weapon skill cost reduction. Shields, block for days, more shields, loads of fun, questionable viability, what's not to love?
