Just some notes and observations as I level as a Lich (have Mage and Necro in the 30s) but they are fairly standard. Level 10 atm.
Main DPS is Hungering Souls, hits much harder than rip and worth losing out on some small values of health drain, I took Necrotic Pact->Isolation and working that circle (around Soul Drain), default spread is found clunky, easy to spam the single heavy hitters (Burizon Magic Arrow flashback )
Secondary DPS is Wandering Spirits, easy to drop at the start of a fight or as you reposition out of AoE as you can cast them on the move. Currently with Souls of rage and heading right that way for the ranged & poison options).
Non specialised triple skellies and Golem as temporary meat shields.
Thoughts and comments welcome.
