Thanks. Though now that I reread I see the issue is the veils working both ways for effects as the only specific exceptions are for creatures leaving/forced to enter. And dismissing a veil is a standard action, so regular casting would be severely gimped under indigo veil.
So what would be good options with Indigo Veil? I know Reserve Feats are (Su) and can pass. Teleportation doesn't require LoE, so I guess stuff like Lightning Leap or whatever its called is in.
Conjuration (creation) spells are best,
especially Shalandra's Delicate Disk, which would be your bread and butter to getting around the veil.
And one popped up while I was typing and checking books..
RAW is stupid here, Wardings are a and Sp effect and AMFs stop that. But AMFs are effects and wardings can stop that.
So the question is which is the most specific of the rules. I know what I'd rule, but there is no hard evidence for either.
As a good rule of thumb for situations like this, check spell level. AMF is a 6th level spell. Indigo Veil is the equivalent of 7th level spell. So I would lean towards Indigo winning.
