Of course you need a Titans for weapon. I have used a cruel Ghost Glaive with good results also. Armor: T-Gods belt, Valk Wing helm, War Travs Boots, I prefer Tiamats Rebuke Shield for additional elemental dmg, Some nice crafted gloves with ias and skill boosts or Lava gouts work well too. Skullders with ias jewel is my preferred armor.

I would add to Senesias skill suggestions that you pump Valkyrie to 10-12 points for tanking cows.
