my standard minion master build

N/Mo
Death Magic 12 + 3 + 1
Soul Reaping 8 + 1
Healing Prayers 10

1 - Animate Flesh Golem
The big boy of the minion world - only alowed one at a time though (per MM)
2 - Animate Shambling Horror
A minion that creates another minion when it dies - the second causing bleeding
3 - Animate Bone Fiend
A lower recharge time than shambling as well as the added benefit of a ranged attack.
4 - Deathly Swarm
Basically... helps a MM to not be totally useless without minions. There will be times when you die or whatever that you dont have any, so I think this is a must (now... its only after a few times round of useless necro that i added it)
5 - Vereta's Gaze
When you die, get rezed use this to get lost minions back
6 - Blood of the Master
A heal specifically for minions
7 - Heal Area
Another heal, not to be used when badies are around. I've never had problems with the AI on this one though.
8 - Rez

The only other skills I'd add would be Vereta's Sacrifice - another very power heal, some say 3 is overkill... But... if you have problems dieing lots, add Taste of Death - a good heal for yourself, i'd bump out vereta's gaze (actually, i think i might do that now...)
