By placing your hand to your mouth and calling out, you gain the attention of creatures around you. For a moment, all eyes snap to you. Some creatures seem reluctant or unable to pull their eyes away.
Any creature with 5 Hit Dice or less is slowed (PH 280) for 1 round. Creatures beyond the radius of the burst might hear the shout, but they are not slowed.
An affected creature under the effect of a haste spell has the haste spell suppressed (not dispelled) for 1 round.
