I'm not a fan of hybrids but I was asked a question in the forums about it and decided to give it a go.
Before yo proceed, please make sure you are aware of the basics of running an EV and Bless Trinity. You can check that here.
Here's the build.
And Here's the Ability window:
Ok so I sacrificed duration a lot to get high-ish range and 40 e per pulse. I also could not get the augment in, unless you want to remove Overextend completely (you probably could in tight maps).
You will encounter 2 problems with the hybrid build, that can be remedied.
1) Low Bless duration-You'll need to just cast more often.
2) High EV duration-You'll have to kill the target right after casting EV. This makes this build very difficult to use especially at higher levels.
Foregoing Overextended for Vampire Leech
You could do this if your team sticks together. This will limit your possible targets though (you need to make sure your team is getting the energy). I also suggest using that Exilus slot for Cunning drift for the 15% added range.
