Undetected / Invisible / Silent Spell / Conceal Spell interaction

[mrspaghetti]

If you're invisible and undetected, when you cast a spell using Silent Spell (which allows you to also get the benefits of Conceal Spell), do you remain Undetected if you succeed at your Stealth check to Conceal Spell? I think the answer is clearly yes, but I would like to poll the knowledgeable forum members to see whether that is a universal opinion.

I would say yes, unless the spell has manifestations of the effect which would reveal you or you're breaking your invisibility because it's a hostile action.

Yes, I forgot to specify that the spell is non-hostile, and wouldn't have any effects (like a Ray) that would give you away. For example, Mage Armor.

I would say yes as well.

If you were unnoticed, I think you would remain that way, provided the spell effect has no observable manifestations.

If the spell effect had an observable manifestation that didn't make your space obvious (such as conjuring a flaming sphere far afield of yourself), I think you would become undetected.

If you were undetected or unnoticed, and cast a spell with an observable manifestation that made your space fairly obvious (such as lightning bolt that could be trailed back to its origin, your space), then I think you would become hidden.

And of course if it's an offensive spell then it will break invisibility and make you observed unless you heightened invisibility to level 4.
