It's a 130-170 pdps claw (total ~200dps after lightning and quality) which gives Ghost Reaver. But wait, GR is right over near CI and the claw leech nodes. Makes this claw seem almost redundant, yeah?
Well, what if that zone wasn't strictly necessary? Templar's got good ES, and there's a circle above scion, and sure that's pretty close to CI (if 6 or 7 points minimum can be "close") but GR's another 4+ points over. Meh.
So...low life or hybrid build? PA's all the way over there, but unless using crown of eyes that hardly matters. A case could be made for either. 10% additional block chance while dual wielding claws, though the other claw would have to be downright spectacular and you'd be using doublestrike. And half the dw block is over by shadow/ranger. Hybrid incinerate with Cybil's Paw, maybe. Or something. Not sure how well that'd work.
For low life, it'd be all the templar ES nodes, possibly the scion ES wheel too, VP and US on the bottom - we're not going to the GR side, anyway. For hybrid, we can simply ignore that section, and...ohsnap, what if we did neither? Essentia's got a pretty respectable 6.68% crit, for a claw, and...aw man, half the crit is over in shadow, including all the claw crit. Oh well. Next time. Cast on crit's probably out then. Cast on damage taken, however, is not particularly dependent on the weapon. That'd require an Aegis. (I've got one, luckily.)
Tricky tricky. Claw, why?
This makes me want to make a hybrid build. Not necessarily with Essentia, but using a combination of ES and HP. I'll list that in another post another day, I think.
