Since DE killed Marked for Death and have no intention of ever reviving it, I swapped it for [Savage Silence] instead. This will one shot pretty much anything that can have a finisher done to it, but it will only one shot that single enemy. Obviously this is meant for situations where kills per second isn't as important as single target damage, for example Rathuum/Index or an assassination mission. I recommend using a zaw hammer so you can also make use of Exodia Might for free healing. This build is meant for aggressive casting, as finishers give you survivability through arcanes.
