Diablo III: Reaper of Souls

From what I've read, Jade Harvester cuts up to 30 seconds off the current remaining duration. Creeping Death makes the 8s duration go up to 5 minutes, and the 16s duration up to 10 minutes for Locust Swarm I believe. When you use Soul Harvest, it cuts 30 seconds from this duration and does that damage instantly. Quetzalcoatl doubles the damage per tick too, so that doubles the damage when you Soul Harvest too.

Ya you combine it with Quezalcotl as it literally doubles the damage. Creeping death is capped I THINK at 1 min or so for damage calc. Basically you throw all your dots out and then soul harvest for some crazy damage. I heard sunkeeper is #1 for 1 handers for the set. Problem is with dots for d3 is the crit is calculated on cast and never again for the remaining ticks. I don't know why they can't do it like wow with individual crits on ticks.
