Anyone ever done any tests to see in exactly what situations this relic works properly?
My character is an assassin and I am considering getting this cloak to 'roleplay' (I hate that word

) his mastery with cloak and dagger.
I have come up against a fair number of mages in the past who are fond of casting dispel magic/true seeing/glitterdust etc and I want to know what spells will make him visible when he is:
a) under the influence of invis/imp invis
b) hidden in shadows
From memory, the cloak grants the effects of the non-detection spell... but does it actually work as such?
Any help you can give me with this one is much appreciated. Thanks in advance.
