Predecessor Builds > Sevarog > The. Tank.

This build has some great survivability, plus good damage.
The enemy team will be running for their lives, and 1v1-2's will be your stomping grounds.

Elafrost and Fist of Razuul are my two must have first items. They give you some survivability, and all your damage
[which will scale with the HP of your following items].

Crystaline Cuirass could be left for later, however IMO, the added mobility of Celestite's 15% MS can really help you avoid deaths, or chase low enemies.

The order of the remaining items is up to you.
