Necromancer Questions:

[Crede]

Being able to break charm at 1-2% is huge for mana saving. I pretty much only used Hungry earth to kill my pet until I got deflux. It gains efficiency as you level, and the added root is nice. Occasionally I would throw in an expulse undead if needed. Pre-Nerf CoS is nice too since you don't have to target yourself and insta invis when flopping around is the double benefit. But if you can't afford it, GGR will get the job done.
