The spells subject can fly with a speed of 90 feet (60
feet if the creature wears medium or heavy armor). The subject
can fly up at half speed and descend at double speed. The flying
subjects maneuverability rating is good. Using the fly
spell requires as much concentration as walking, so the subject
can attack or cast spells normally. The subject of a fly spell
can charge but not run, and it cannot carry aloft more weight
than its maximum load (see page 142), plus any armor it wears.
Should the spell duration expire while the subject is still
aloft, the magic fails slowly. The subject drops 60 feet per
round for 1d6 rounds. If it reaches the ground in that amount of
time, it lands safely. If not, it falls the rest of the distance.
Since dispelling a spell effectively ends it, the subject also
falls in this way if the fly spell is dispelled.
