Dazed does affect you mentally. Its not like a flash of light or anything restricts your movement or slows you. I temporarily leaves you mentally able to react, or to react less efficiently.

I would say its a mental effect.

That was my take on it as well.

It's not really a physical effect, hence why I was leaning towards it not affecting them.

I have a broken, broken "boss" encounter to finish up this evening then :)

Daze effects should all be mind-affecting Enchantment (compulsion) effects (All compulsions are inherently mind-affecting).

Where is the daze effect coming from (both daze and daze monster are compulsions)? I can answer more in specific if I know that part. If you have a daze effect that isn't mind-affecting, there may be another reason.

Ah, I've found one daze effect that isn't explicitly mind-affecting. The dazed effect of blasphemy, which is Evocation [Evil]. The same goes for order's wrath. I'm inclined to think this is an oversight, and these effects should be mind-affecting, since the confused effect from similar alignment spells isn't explicitly mind-affecting, and confused should always be mind-affecting, IMO.

Short answer: By the literal RAW, daze effects that don't say they're mind-affecting aren't. By common sense, they are mind-affecting, and immunity to M-A effects grants immunity to daze effects.

Thanks, glad to know someone else shares my surprise that some effects weren't.

Blasphemy was the first one that piqued my interest when I also was trying to see if daze effects (in spells, at least) were uniformly described as mind-affecting.
