PvE N/Mo Minion Master Guide:

Attributes:
12+3+1 Death magic
6 or 8 healing prayers
Rest in Soul Reaping

Skills:
1: Deathly swarm (or other direct damage spell)
2: Heal Area (or Karei's Healing Circle)
3: Blood of the Master
4: Optional
5: Pick an additional minion
6: Animate Flesh Golem
7: Animate Bone Fiend
8: Rebirth

Reasoning: 

Deathly swarm is used when there are no corpses or you need to tell your minions to attack somewhere out of line of sight.

Heal area is used as a self-heal that can also help support minions.

Blood of the Master is very important, and should be used frequently when not summoning minions or running away.

Optional:Signet of Capture, Verata's Sacrifice, Infuse Condition, Heal Party, and Dark Bond are all fair choices, as are many others.

Additional Minion: See below for minion comparison

Animate Flesh golem: If you have Factions, get it, otherwise use Bone Horror

Animate Bone Fiend: This is the highest damaging minion (save Golem).  Use it.  A lot.

Rebirth: This skill is good.  Trust me.

Additional minion choice: (See Minion comparison guide for damage)

Animate Bone Horror: Cheap, durable, best when you are tight on energy and need tanks.

Animate Bone Minions: Not very useful in battle, very weak, very cheap.  Best when you need speedy meatshields.  It's positive energy gain with Soul Reaping, so the main cost is the corpse and the time.

Animate Vampiric Horror: Statistically the same as Bone Horror, but decreases pressure on the healer, while costing more and taking longer to recharge.  Best when there are many enemies (which means many corpses, many soul reaping bonuses, and many things attacking).

Gear

Armor: Minion Master's or Cultist's/Tormentor's (for non-Factions, or if you switch to other Necromancer builds a lot) with a +1 death magic scar.

You must use Bloodstained Boots. 

Runes: Superior or Major Death magic (See minion damage tables for comparison...coming soon

Minor Soul Reaping

Minor Blood magic (Optional)

Vigor Rune (Minor if you're poor, Major if you're rich, Superior if you have more gold than you know what to do with)

Weapon/offhand: I consider the weapon/offhand approach significantly better than the staff approach, because it allows for you to double up on the faster casting and recharge modifiers.

Faster recharge of Death Magic is most important, followed by faster cast of Death Magic.  If you must use a staff, chance at +1 to Death Magic is good for a suffix, and either hp or energy as a prefix.  Collector and crafter items can easily get the recharge/cast modifiers at max.

Note: According to some extrapolation in the minion damage comparison guide, 20% faster recharge is over twice as good as 20% death magic +1, assuming you generally operate below 10 minions.

Strategy

Use Flesh Golem first, and keep an eye on it for when it dies, so you can replace quickly.  Bone Fiend should be used whenever it is available and you have a Flesh Golem.

If you're being attacked, run away and use Heal Area.  Rebirth should not be used in battle while there is a corpse available, as Blood of the Master or a new minion is often a better choice.  This does not always apply.

As a Minion Master, you are a large source of damage and damage absorption; your death will often signal defeat.  It is not only the monk's responsibility to keep you alive, you need to avoid damage and heal yourself, along with using Blood of the Master smartly (Ex. Not when your hp is low or you're being attacked, or when taking damage would put excess strain on the healer).

Hopefully you'll have a good time with this build.
