Details

There's nothing special about this really. There is, however, one interesting anomally: While UnitHealth will return percentage values for "target" and "mouseover", this one seems to return the actual mana points for all possible targets.

This is also the mechanism for getting a unit's rage or energy, since there were no corresponding UnitEnergy or UnitRage functions. You can use UnitPowerType to figure out whether what you're getting is Rage, Energy, or actual Mana.
