Spell Details
Effect
You conjure a wall of drifting mist that forms where you point within range. The fog heavily obscures sight, unable to see throug it, and when in it creatures can see only 3 feet. Inside the mist muffles sound and diffuses light, dimming torches and lanterns to 3 feet too. Creatures inside or behind the fog gain +2 DEX Quick (for stealth/evasion).
Scaling
At 4th level, wall may extend up to 40 feet in length and gain +3 DEX Quick. At 6th level, wall can now be up to 60 feet in length, 20 feet high and 30 feet thick
Special Notes
A strong winds, heavy rains, and other extreme weather has no effect, through it passes through it. If cast underwater, it instead creates a cloud of silt and bubbles that functions identically.
