I mean like this: XXX thinks he is incredibly ugly and uses azure magic to have a cute face. Does he project the face he wants to have to other minds or does the illusion cover his face like a second skin?
Well some kind of 'hologram' would be made of light, so I would say it would belong to Crystal way (which indeed does everything). Azure way seems to rely more on acting on one/others' minds and on air fluxes.
Back on the 'no dice you heretics' thing: seriously? How can you not get the magic there is into solving something on the roll of a plastic polyhedron, may it be virtual? There are some horrible flaws in action-interpretative RP; you'll end up knowing how any situation will likely go with a given RP partner, and it takes serious writing skills in the used language. So not only you reduce the population you'll enjoy practising it with, but you'll know how things will end up with every one of them.
I think we could use a '/roll [skill / stat]' command, that could be extended as 'roll [skill / stat] (against) [player] [skill / stat]'. Degrees of success to introduce and balancing to be thought of.
That said, I'll precise this place must be the only forum I haven't seen flaming after the interpretative RP VS moderative RP thing has been uttered.
Now about Azure Way. Whenever one casts a spell you can see fantastic light effects, so any use of an active spell would be instantly detectable. If so, up to you to break the caster concentration by punching him/her/kra in the face. The 'nature intuition' spell sounds to me like a plain mind reading spell, and we know there are spells to convince someone of something that isn't real, or to mute someone (noticeably in order this one can't cast any spell).
BUT we know there are Azure passive/buff spells (such as Dome of Perfection), and one that allows you at least to determine with certitude whether you're being lied to, or if the person in front of you is mistaking the orthography of an exotic shadowcaster's name (Dark Wanderer uses it), which might as well be a lesser form of nature intuition. I think it would be reasonable to imagine 'lesser casts' of these potentially cheaty Azure spells the same way.
