Stealth + Silent Spell + Obscuring Mist

[Korwynne]

My latest thought:

A spellcaster passes a stealth check to enter a room - remaining at the edges of a room and unnoticed by an enemy (the caster is either invisible or in darkness).

The caster then wants to cast "obscuring mist" - a non-offensive spell that creates a mist that emanates from the caster's position. This is a standard action and the PC has silent spell, but does not have quicken spell as a feat.

For casting the spell, should the caster roll another stealth check? If so, what modifier would apply?

For the enemy, the mist would be a clearly visible action. Would they notice it at the onset and therefore get any bonuses in pinpointing the caster's location?

Thanks in advance!

Afaik this is GM purview.

The spell's somatic components are irrelevant because of the lack of vision. So no stealth check to cast, the wizard isn't being noticeable. That's easy.

As far as your target noticing the mist and deducing the wizard must be in the middle, that's entirely up to how smart you want to play your enemy.

Remember though, that your enemy wouldn't know you moved->cast. For all it knows you cast->moved, so you aren't necessarily in the center anymore.

Ahhh, good point. I was also thinking from the standpoint that there are higher-level fog spells where you pick your point of origin (they don't need to equal where you're currently standing). Thanks for the feedback.

Every (I think) fog spell except for obscuring mist lets you pick the point of origin, you're right. I was just assuming that if you were talking about an enemy who knew the caster would be at the center when the spell was cast, that he'd made his spellcraft check and pegged it as obscuring mist.
