So I'm just going to go out on a limb here and say that Scalp is probably the most powerful skill I've come across in terms of clearing floors. Tho' I haven't been pushing to surf through, I've just been farming between 500 and 700 for what feels like eons.
I threw this together yesterday with the bit of variety of crystals and mythstones that took me FOREVER to accumulate - and I'm happy with how it's turning out so far.
A couple of changes need to be made here and there. Plan to have 100% pierce chance - 10 all talents - 10 all skills. I also use vampiric touch with blood magic and void alchemy, when I use my Imp.
This build is pretty much a homemade version of discordance with the benefits of alchemy' DMG. With all that clearcast and specialist' it's no wonder I have up to 20 twisters and scalps parading around me a annihilating everything instantly. Epics included, depending on HP% and heals.
I'm busy with a helm that'll have the epiphany bonus, harmony and vampiric touch. Hopefully get the attack speed obsidian for it.
and block for my OH.
Purely PvE build although two item swaps make it a great PvP build too. Not sharing that tho'
Please gimme some suggestions that'll maybe tweak or improve it. Bearing in mind it isn't complete.
