Thicken Air (3.5e Spell)

''The air seems a little hazy. As you enter, it's like you're pushing through a wall of pillows.''

You generate an area of thick air, which slows the progress of those moving through it. Creatures speeds are cut in half, ranged attacks that pass through it take a -4 penalty to attack, and those falling through it max out at a fall speed of 60 feet a round, taking no damage as if they were using feather fall as long as they are slowed. The thick air is difficult to see; creatures must succeed on a DC 20 Spot check to notice the altered area.
