Hammer Dagger

The idea is stunning your opponent with Hammer so all your Daggers will attack instantly.

Bloody Daggers are the best because you'll get a lot of Vampirism that's important to not die to Spike builds.

Acorn Collar is important to crit.

Hero Longsword is nice to have but not necessary. You could use Shepherd's Crook aswell.

To raise your damage you'll need empower.
Best source is Amulet of Steel. Otherwise you can use Carrots or Fanfares aswell.

You'll need a lot of Stamina because Hammer uses 3 Stamina per attack. That's why Heroic Potions are important, they give you Empower aswell.

Winged Boots, Cap of Discomfort and Stone Helm are good defensive options.
