How to play:
In this build there is only one skill that deals damage - Barbed Signet. Use it from time to time.
First disable foe's elite skill by using Signet of Humility. Then try to interrupt with Leech Signet and use Signet of Humility to deprive foes from energy.
Signets have quite long recharge time so you have to use Keystone Signet to use them faster. But after that also Keystone Signet will need to recharge. That's why before you cast Keystone Signet use Mantra of Signets. Now you can use all signets for quite long time. :)
If you choose Mantra of Inscriptions then cast it before fight.
Demonic Flesh is one of best Enchantment in game! Try to have it always. Cast it even if you have small amount of life!
