A slow spell causes affected creatures to move and attack at half their normal rates. It negates a haste spell or equivalent, but does not otherwise affect magically speeded or slowed creatures.
Slowed creatures have an Armor Class penalty of +4 AC, an attack penalty of -4, and all Dexterity combat bonuses are negated.
The magic affects a number of creatures equal to the spellcaster's level, if they are within the area of effect chosen by the wizard (i.e., a 40-foot cubic volume centered as called for by the caster). The creatures are affected from the center of the spell outward.
The material component of this spell is a drop of molasses.
