The better, more conclusive test, would be to simply do the following:

Take two Theurgs, script the first to do "Master, Slave, Astral Shield, Hold, Hold, Spells". Script the second to do "Master, Slave, Astral Weapon, Hold, Hold, Spells". If both of them end up with astral weapon and astral shield, it means a unit CAN simultaneously be a master and a slave.

Tried it with 2 lizardman shamen. All spells should cost 24 fatigue, including encumbrance.

Round 1: Both cast slave. Each has 24 fatigue.
Round 2: Both cast master. Each has 48 fatigue.
Round 3: One casts Astral Shield and one does nothing. Both have 72 fatigue. Both are shielded. Only one casting has taken place, but both get the fatigue as if they had cast the spell and one shaman didn't do anything.
Round 4: Similar to 3. One casts Astral Weapon, one does nothing, and both end up at 96 fatigue.

So based on this test slave and master work together, but they work... oddly.
