All creatures affected by the spell Haste have their rate of movement doubled, gain a bonus of -2 to initiative and receive an extra attack each round.
When this spell is cast, all creatures affected function at double their normal movement rate, gain a -2 initiative bonus, and receive an extra attack per round. Thus, a creature moving at 6 and attacking once per round would move at 12 and attack twice per round. At the instant the spell is completed, it affects all ally creatures in a 30-ft. radius centered on a point selected by the caster (thus, creatures leaving the area are still subject to the spell's effect; those entering the area after the casting is completed are not). This spell is not cumulative with itself or with other similar magic. Spellcasting and spell effects are not affected. Note that this spell negates the effects of a Slow spell.
