Of course, the wizard must be facing the creature, and the creature must be within the range of five yards per experience level of the caster. Creatures with 1 to 30 hit points are stunned for 4d4 rounds, those with 31 to 60 hit points are stunned for 2d4 rounds, those with 61 to 90 hit points are stunned for 1d4 rounds. and creatures with over 90 hit points are not affected. Note that if a creature is weakened so that its hit points are below its usual maximum, the current number of hit points is used.
