A nice and balanced build featuring a healthy pool of life - around 4-5k depending on gear, focusing on crit to obtain high dps, now updated for release version changes.
Projectile damage and crit nodes are your best friends on this build. This is because crit scales extremely well late game, and your damage type will be mixed, making projectile damage nodes more effective than pure physical or elemental damage nodes.
During early leveling it might be better to pick up damage nodes instead of crit nodes, then respec into crit late game using orbs of regret. This because crit is most effective when you have a reasonably high chance to crit.
There are two ways to work with blood magic. One way is getting the passive, which you will want to get as soon as your health pool can sustain it, typically around level 40-50 with atleast 2k life. If you go for the passive node, I would recommend not using any auras, because it wouldn't be worth the life cost. This means that your solo dps wont be that great (but decent enough) but your party dps will be very good.
The other way is to use blood magic gems on all your active skills. This allows you to use atleast 2 auras on mana with a reduced mana gem, substantially boosting your solo dps, despite spending that red socket on something other than WED. It also frees up all those passives to be used on more damage / crit nodes.
As you can see I went with using BM gems, as I tend to play more solo. Get as much crit and life on gear as possible. Life flasks with instant recovery are a must for sticky situations, and pop a diamond flask for bosses and watch them just melt.
Link Frenzy with life leech for survivability and Blood Magic, then add as much damage as your links allow. I went for WED and Faster attacks on a 5link. LA gets the conventional Blood Magic-Chain-LMP-Life on Hit
4,3k dps on LA with Chain and LMP, 30k on Frenzy (with current gear), this with 6 frenzy charges, Wrath/Anger and 5-linked skills. 4,9k HP.
Additional skills I use are Enfeeble / Critical Weakness curse linked with increased AOE, skeleton totem with blind on attack for vastly better survivability against bosses, and Lightning Warp - Because its awesome and cool.
I'd like to add that this build works with more than just Lightning Arrow. Want to use Ice Shot? Spec into Piercing and switch Enfeeble out with Projectile Weakness curse and switch chain with faster attacks. Boom, there you have a very good piercing ice shot build that I actually used myself before switching to LA. :)
If you have any questions feel free to send me a PM or contact me ingame!
I was very happy with this build, you can read some pages ago.
Sadly not more time to play, so I'm liquidating my crit-LA, it was very fun while it lasted :))
If you search perfect crit gear in Domination, just PM. Sold some pieces already but the most precious one is still available, the bow:
I as well may sell gems, but not sure yet since all are nearly 20. Critchance with Vaines build and Maligaro's around 60%.
