It’s what I’d like to test next.
Yes, I distinctly remember a build posted here like around 2 months ago: Dark One Cabalist that did exactly that. Try searching for it. Build was built around Dark One Set, two Ravenous Greens and a Blood Orb of Chton. Or was it Conduit for vita DEE + green off-hand, don’t remember.
DEE with blood orb is in fact the only actually working vit decay build. Add that abomination devotion proc and manticore and you’re done, really simple.
Bonus points for not having to use the Dreeg set either.
Ahh - I looked at this briefly and iirc the Dreegs set + Blood Orb had potential + some cast speed gloves. I didn’t have the full set, though.
I also thought 3 of 4 dark one’s set + Bloodfury shoulders (I like the proc) would work well.
The biggest issue was that in most every case (except full dregs), Morguuls Pistol seemed to be the best option. So I ended up having more interest in building around those pistols instead of DEE.
Standard spam vit devotions: dead god, Rattosh, Manticore and other stuff.
And Vit DEE would have had at least 12/12 SoC in my books. (leech and proc).
For what it’s worth…
What about a Occultist Shaman for it?
I’ve made Dark One Conjurer with Conduit for Vita DEE, transmuted DEE, Sigil of Consumption and Corrupted Totem. It was meh, kinda slow. I think spam DEE would be even worse. But you can always try, Conjurer is a very versatile class combo, can always respec to something else.
You could try something like this with Dreeg Set:
Quick and dirty DEE Spam Vit convert with dreegs set
I threw a point in Second Rite because I couldn’t juggle the vit resist, but I’m sure different boots or such could solve that. And I probably messed up the some skill points when I pulled those 2 at the last minute…
I think you’ll have energy problems on a DEE spam, so I went that direction.
(^it would be nice to see that dreeg set used for something!)
Thanks guys. I had some friends help me out as well. With the link above and a version of spammable vit DEE Dark One’s set, I have two main contenders to test in the playtest. I’ll do my best to make sure DEE is viable and fun in all its intended forms.
You kinda missed Corrupted Storm Totem, mate.
he went for sigil instead
He can have both there.
Well, I have in testing Warlock build spamming vita DEE based on Dreeg’s set and sphere if I remember correct.
Vitality DEE is a favorite of mine. I made a topic about it a while ago: http://www.grimdawn.com/forums/showthread.php?t=77174
8/10 Spectral Wrath and no overcap? Madman 
You kinda missed Corrupted Storm Totem, mate.
Ah, that’s a fair point.
If desired, Wendigo could be changed to Storm Totem +transmuter for more damage. Wendigo is a bit of extra heal security, but SoC should be plenty; and with SoC you don’t have to be in the radius to heal (only the mob needs be in the radius), unlike Wendigo . So…Wendigo may not mesh with SoC playstyle, depending.
It’s flexible and the points can be moved around. The main objective was to max DEE for the spam trial.
Edit: or can move 11 points from Wendigo into Terrifying Gaze for absolute maximum DEE skill testing. (Terrifying Gaze returns are minimal, though, imho)

Interesting.
The odd thing about the Pandemic Dagger is that it has no cast speed but it does have skill % reduction, so it’s kind of in the middle.
Here is a DEE spamming Vit/Acid/Poison Cabalist a threw together a number of months ago.

Note it’s not a fine tuned build & could be improved. I’m not a fan of the poison, preferring acid/poison nuke rather than DoT playstyle (& you’ll need to GD Stash the greens).
Have not played the toon so cannot offer any advice as to the performance of the build.
Feel free to develop further.
Cheers.
