Weird Arcana - Olorin’s Acquiescent Fog (New Spell)

Here’s a new spell. With any luck next weekend may give me the time to finish that Green Book entry on the Alalas.

I designed this spell for my (no yet started) G+ sandbox campaign based on the Forgotten Realm setting. I managed to run one 'test drive' session two weeks ago, mainly to show the G+ Hangout tool to my old players. It worked well above my expectations (I'm and will always a fan of "true table-top" sessions). Because our session was scheduled to last 2 hours, the entire game was a lot more focused and organized than previous campaigns (otherwise we would barely finish one encounter or NPC interaction). This test drive convinced me to keep in touch with my old group and to try new things (technologicaly speaking). When we really start the real thing (hopefully on April 2013), I'm ansious to see how things will go. 

Olorin’s Acquiescent Fog

Transmutation
Level: Bard 2, Druid 2, Sorcerer/Wizard 2, Witch 2
Components: V, S, M (a lit smoking pipe)
Casting Time: 1 standard action
Range: 30 ft.

Effect: The caster controls natural of magic fogs around him
Duration: Concentration (see text)
Saving Throw: None (harmless)
Spell Resistance: No

This spells allows the caster to control any mist, fog, smoke or smog around him. He can command the fog to assume shapes, open corridors in the mist or even to dismiss it entirely from a 30 ft. radius area centered on him. The caster must have line of effect to the fog.

If the caster attempts to confuse other creatures by creating shapes within the fog, allow the targets a Perception check (based on sight) to determine the false nature of the vaporous forms (as a suggestion, allows an opposed check between Perception and a caster level check).

Olorin’s acquiescent fog also allows the caster to see 30 ft. inside any mist, fog, smoke or smog.

Once a caster ceases to concentrate, the spell remains in effect for another 1d6 rounds.

Olorin’s acquiescent fog is known among druids as mischievous mists and among witches and bard as witchfog. Druids require mistletoe as a material component.

Finally, Olorin’s acquiescent fog doesn’t work properly on mists created by magic (as fog cloud). The caster must succeed at a Spellcraft check (DC 20) or the spell is interrupted and he becomes confused for 1 round.
