Grand Deception

Spend 1½ Actions in attempt to create a complex illusion that fools the senses in a 10-meter radius around you. You can make terrain appear different, create phantom structures, sounds, and smells, and disguise yourself and allies. Creatures must succeed on an INT Check against your FCS Check + 5 to recognize the illusion. While within the illusion, you and your allies gain +3 to Stealth checks and are considered Unseen to creatures that failed their check. The effect lasts for 10 minutes.
