The descriptions states:
'
Illusions also fail to conceal the target, granting any onlookers a +20 bonus to associated Sensing tests'
Thus, in my opinion, I think the 'conceal' part is key here; the bonus would apply only to things that
conceal (i.e. hide) a target. Thus I'd say the +20(!) bonus would apply against spells like like 'Nobody Here, 'Notice Not', 'Cloak' and possibly 'Innocent Activity', 'Phantom Warrior' and 'Displace Image, NOT other illusions like 'Monstrous Mantle' or 'Best Face'.
But even IF it applied to any illusions, lets not forget that the whole point of illusions are that you BELIEVE they are illusions. Even IF casting Sunlight on a target using Monstrous Mantle would give the +20 bonus.... why would you cast that spell on the target IF you have no reason to know or suspect that there is an illusion in effect?
nothing about the illusion forces you to believe it is not an illusion. you can still think that something is (or at least may be) an illusion and not be able to see through it, and use spells to help with that. in fact, there are a few spells in the illusionist spell list that are very specifically designed to help you see through illusions when you make sensing tests.
this spell (if you have a way to cast it on others) is not really any different; you think that wall might be an illusion, but your best efforts have not been able to reveal it as one. it feels real, so you can't just walk through it, and it looks real, so you can't see through it, but you have this spell that you can cast which you know makes it easier to see through an illusion, so you decide to use it.
even after using the spell, you could potentially still believe the wall is a (very convincing) illusion even if it doesn't let you see through it, for that matter. of course, it is also entirely possible that the wall you just got a step 30 or 40 sensing test against and didn't see through any illusion is still there for you because it is in fact a real wall, too; the spell doesn't tell you one way or the other, it just lets you *try* to see through any illusions that are there.
and incidentally, i'd say monstrous mantle probably is concealing the target, at least to some extent. the bonus to physical defence doesn't make much sense to me unless it is.
