I am looking at Constellations and “Ghoul” gives 4% of Attack Damage converted to Health.
Does this apply to Casting powers? and even DoT powers like Inquisitor’s “Word of Pain”?
Or does this life leech only applies to “weapon damages”?
Thanks!
Only to weapon damage.
Oh that sucks.
Do different sources of ADctH stack? So, if you had devotion nodes &/or ADctH from items, would they increase the life you get back from non-weapon attacks that already have ADctH (such as Twin Fangs & Devouring Swarm)?
nope, only on weapon damage component.
It’s a question from the Praetorian?
Booo, so there’s no point in getting additional ADctH if you’re only using Devouring Swarm as the leechable attack. 
The forum titles relate to posts rather than join date don’t they?
Most forum titles do. However, the Praetorian title denotes someone that Crate has invited to playtest game pre-release. Since Crate prefer a wide testing base Praetorians are a mix of all kinds of players, some long serving members of the forum, others more recently joined.
Ahh, makes sense, thanks. 
Nope. You need to focus on getting +% vitality damage, lowering their resistances and their life leech resistance (like the skill of the Rattosh, The Veilwarden devotion)
Yeah, I’ve got a build that gets -10% vit resist added to Bloody Pox & -64% from Devouring Swarm. Didn’t notice how much % vit damage you get from the Veilwarden though, might have to see if I can work that in somehow.
I think Veilwarden is a must for vitality builds, soo many mobs have enormous vitality resistances. If you want you can upload a GrimTools and perhaps we can help you out?

I think the gear looks ok (feel free to make suggestions though), but the devotions are probably up for grabs (though Twin Fangs does proc a stupid amount from Bloody Pox so I’d probably keep that).
I would grab Curse of Fraility for the resistance debuff.
It is also strange that you do not have neither Turtle shell, ghoulish hunger, tip of the scales and Nature’s Guardian bound to skills.
Does the movement speed debuff from Curse of Frailty stack with the one from Grasping Vines (presumably with some diminishing returns, 75% from GV & 50% from CoF)?

I wasn’t going so far as to do the devotion bindings, since I wasn’t entirely sure what would be best/needed/etc. The only devotion that I’d definitely want to keep is Bat, the rest of it is for defensive purposes IMO ('cause the transmog on Bloody Pox is awesome for making things a bit more interesting with Champions & no-doubt nemises. Nemisees? Nemiseses? Nemisii?).
Mind you, the Veilwarden devotion only adds 180% vit damage (plus 650hp & some other resists) which is on top of the current 2,200%, which is an 8% increase & I’ve no idea what you would be giving up (since the devotions in the link above aren’t exactly min-maxed…
Edit: It also seems like the boss with the highest vit resist is Ravager of Flesh/Souls/Minds @ 136% so with Devouring Swarm, Curse of Frailty & Bloody Pox that should be reduced to a small positive number & everything else should have a decently negative vit resist.
If you get a mob down to 0% vit res without veilwarden, then veilwarden nodes and proc gives 1.08*1.25 = 1.35 = 35% extra damage. That is pretty nice if you ask me.
Well, it would appear that the devotions on my lvl 49 character were somewhat different to what I put in the above link & I was heading down to Veilwarden anyway. So I’ve updated it to reflect that, get Veilwarden, Curse of Frailty (mainly for vulnerability) & while I do get more dps (+2,409% vit damage v +2,229%, 2.7k OA v 2.5k), the HP is quite a bit lower (15.4k v 19.4k) & I’m not sure how that will work in Ultimate what with the transmuter for Bloody Pox.
15.4k HP seems OK for Ultimate to me. I’m currently in Ugdenbog Ultimate with a little more than 14k but my char has a lot of ADCtH as it’s using weapon attacks most of the time. I died once to Kra’Vall and once to being careless (on total during that Ultimate run)
A related question. Does (global) ADCtH apply to spell like abilities that use %weapon damage (such as a Necromancer’s Bone Harvest) or only direct attacks (basic attack, cadence, savagery …).
What about passive attacks using %weapon damage such as Spear of the Heavens proc?
It only applies to the weapon damage component.
Unless it reads say “y% attack damage converted to health on XXX” then it applies to the entire damage (not dot damage though) that that skill deals
For instance look at Bat - Twin fangs devotion. The Adcth appiles to both the flat pierce, vit and the wpn dmg.
Or the adcth on Heart Seeker modifier on Phantasmal blades. the adtch will apply to both the wpn dmg and the flat dmg on Phantasmal blade skill.
