Juggernauts will be using Strength-based Armour that is skewed heavily towards physical protection, which is excellent for this Build. Wits will help give you needed Initiative to get into combat early as well as bump your Critical Chance. Strength will not only increase the damage of your Warfare Skills if you use a weapon that scales with Strengthbut it will increase the damage of Polymorph Skills. Juggernauts are going to focus primarily in Strengthonly putting some points into Wits and Constitution as necessary. I am not using a Shield, simply because I have a really good Two-Hander at the moment, but usually my Armour would be much higher and damage much lower. The purpose of this Build is to deal punishing amounts of damage to the Armour of various enemies, while at the same time keeping them Knocked Down or Petrified and out of the fight.
However, this Build takes advantage of Geomancer Skills that reward players who deal physical damage and a Polymorph Skill that deals earth damage, but scales off of Strength. At first glance this seems like a bad idea, because splitting damage types generally reduces your overall DPS.
Juggernauts focus on pure Strengthbut deal a mix of physical and earth damage to their enemies. Since the game is extremely difficult this has come much more into focus than one would expect.
