Problem with Enemy Affecting auras...

They don't. At least, not reliably.
I've got them set up to affect "enemy, not self, neutral", but they also affect my own units, and one, based on Life Regeneration Aura, is unreliable, and only affects some units some of the time.

They're based on Unholy Aura, Command Aura, Endurance Aura, Devotion Aura, and Life Regeneration Aura, all given negative values (which work fine), and they're all on seperate Ward summons.
Can anyone give me an idea what's wrong here?

try putting air, ground and enemy in targets allowed...that is what i usually put for all negative spells. also try using unholy aura instead of life regeneration, they do just about the same thing.

Actually, I worked it out.
Not Self overrides the others, so the aura affects anything except the user.
Also, the Life regeneration aura only works on wounded units. But I like it that way, so I'm going to leave it.

It's worth noting that spells are hardcoded as "good" or "bad" and so the buff will make the unit's icon show up normally or covered in red, depending on which kind it is. For an enemy unit, you'd want it to be red in the best possible scenario, so you might want to use "bad" auras as much as possible, like the Tornado Slow Aura instead of Endurance, if you can.

hmmm can't you simply use a different buff? or perhaps even use a color code in a buff's name?

The latter will work.

'Preciated. I knew about that, but thanks for reminding me.
