Blood Magic: Life Transfer (elite), Life Siphon, Demonic Flesh, Strip Enchantment
Curses: Faintheartedness, Parasitic Bond
Illusioin Magic: Conjure Phantasm
Other: Ressurection Signet
Weapon and Armor:
The best choice for armor is Scar Patterns because they add bonus energy which is quite important in this build.
For weapon use Staff with bonus to HP because with Superior and Major runes there is small amount of life. Staff should have "Improve skill cast/recharge using Blood Magic".
How to play:
There is no big philosophy in this build. Just follow the target and cast skills. First use Life Transfer and Parasitic Bond to cover LT. Conjure Phantasm is great skill for spamming with degeneration. Remember that you can make only -10 degeneration at once. Faintheartedness and Life Siphon is only adjunct for skill mentioned above.
Demonic Flesh is one of best Enchantment in game! Try to have it always. Cast it even if you have small amount of life!
Use Strip Enchantment when you see that foe has some regeneration of life (Healing Breeze of something similar).
