This is the support necro build used for "Rat" runs or Rathma runs. There are many variations of this build; however I like this one due to the toughness factor. Even at lower paragons you can survive in some high level rathma runs. I was running 107s with about 950 paragon with no issues. Each item on the build is used to reduce cooldown, add toughness, or increase speed. The 4 piece pestilence set bonus gives you serious toughness and will cast a corpse lance everytime a corpse is devoured. It's a fun and safe build that will allow you to run these fast paced rathma urns.

For this build max movement speed with paragon and gear and then everything else into vitality. (This is a support build so it does no damage in the runs.)

For offense max cooldown and then attack speed then chance.

For defense start with life the armor.

utility go with life on hit and resource cost reduction.
