Poison Blademaster build (at development)

Greetings Grim fellas.

I’m building a poison DEE Witchblade provided on this link: http://www.grimdawn.com/forums/showthread.php?t=61983 , made by experienced players who dominated crucible gladiator for help new players to achieve that strenght.

The DEE witchblade is a caster build, very resistant, the way you play it is cast and run around while mobs are melted by dot.

I was thinking how I could improve the resistance at the point to facetank gladiator without sacrifice the damage (at least just a bit), when I got the idea to try nightblade tree instead occultist.

This the build I’m following: https://www.grimtools.com/calc/vNQRvbv2

This is the build I go the idea to do: https://www.grimtools.com/calc/eVLBloPN

I would like to see what do you think guys. I’m really interested to have sure if this build are viable. Thanks and sorry the english.
