Necro charm killing, what spells?

[Widan]

I'm aware of the general method of charm killing at 54+: charm a pet, root some mobs to attack pet, CoS break charm, root/tap pet down, recharm new pet. I'm just not sure if there is anything I'm overlooking. General spell bar should look like:

Root
Charm
Tap
Lich
FD


What would you use for the last 3 spells? Manaskin probably to add an hp buffer, though you can always just mem this in between? Undead nuke maybe incase you need to burst something down?

Charm
Root
Tap
FD

^--These are essential.
I usually went with
Screaming Terror (Mez)
Splurt
Cessation of Cor or Pyro (1 min disease or 2 min fire DoT)
Lich (Wild card, exchanged for refreshing DMF / Shield)

The two extra dots because I don't know of any place you can charm kill that has only undead. Even in HS there's a healthy live population.

I mean I've yet to try it but 2nd floor of CoM and Karnor's basement seem to be the two places people suggest...not enough undead there?
