This build is exactly the same as the build you would use leveling from 51-70. Both you and your pet become incredibly difficult to kill.
Fighting with this build means your pet will be tanking for you while you stay back and wand/dot the monster up. You'll also want to use health funnel to keep your pets health up.
Shadowburn is available to provide a quick end of the fight burst giving you your soul shard back as well.
