Assassin/Ninja Help Heavy Melee (grimtrap?) Assassin Build

I want to make an assassin build focussed on heavy melee to abuse quake, vanish, mana steal and life steal.

No price limit, I was thinking grimtrap/dawnbreak build but feel free to suggest anything if you think it would be better.

Basic heavy melee. Personally I prefer mech core over drain but drain is probably better. You can swap fractured for downfall. Also you could use anvil crawler over grim because the vanish cost will get annoying seeing as you want to vanish after every attack.

 

This is the Dawnbreak heavy melee I use on assassin. StormDragon is right, the +1 vanish cost on grim is very punishing, especially since the base cost of vanish was increased.

 

i dont recommend using grimtrap in heavy melee, the +1 second spell cost is really annoying.
