Blood 12 (8+1+3)
Beast mastery 12
Soul Reaping 11 (10+1)
1. Lifebane strike
Just for dmg and the possible life stealing wich is good
2. Vile Miasma
Gives some decend dmg and ofcourse the vile miasma degen when somebody was under effect of a condition
3. (Whatever you like) I use Feral lunge but you can use whatever you want.
4. Poisonous bite
Gets your enemy poisoned ofcourse ey
5. Heal as one
Good self/pet heal wich can be usefull in some situations.
6. Comfort animal (if you are confident swap it out for something else)
7. Charm animal (the key of this build ;P)
8. Rez siggy
Strategy: First of all this aint a farming build....
With that aside lets talk it over first off all get your pet to attack the target lets say a fungal wallow? Cast poisonous bite to get the wallow his deserved poison... After that cast Vile miasma to give him some extra degen en just keep wanding

Concerns: Well a dead pet is a dead build?
Advantages: Most people wont attack da pet when it belongs to a necromancer

Dont be to harsh on me plz its the first time i have posted a build on these forums hehe.... if you got some suggestions though tell em.
