Have you considered dropping Lotus and the one point in Revenant and take Oklaine’s Lantern instead? Would give you 25% trap resist, and the rest of the stats aren’t bad either.
Very impressive build! I love seeing successful Defilers. I can’t help but like the class despite its weaknesses.
Thanks, @AdequateSubject!
Lantern suggestion is pretty cool, honestly didn’t notice it was an option. It will probably take 10-15 seconds of Crucible clear timers, but I doubt it’s going to help in SR. Losing 3% physical resist and some vitality resistance overcap might expose this Defiler in a way that it will stop being consistent in Crucible (when you have 14% total phys res, losing 3% will hurt).
I love the build. nicely done as usual. I don’t have time to play at the moment, but this is the kind of build that gives me the urge to level a class I don’t have 
and +1 / <3 for the Fester use.
Uncle Fester approves
Build is still pretty solid in 1.1.4.2 Crucible timer is now slower by 20-30 seconds due to Crucible being tougher than it was in 1.1.3.1 when the build was created. However, Build can still farm Crucible in 7-8 minutes very consistently and still absolutely refuses to die.
