Description
The subject can fly at a speed of 60 feet (or 40 feet if it wears medium or heavy armor, or if it carries a medium or heavy load). It can ascend at half speed and descend at double speed, and its maneuverability is good.
Using a fly spell requires only 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, plus any armor it wears. The subject gains a bonus on Fly skill checks equal to 1/2 your caster level.
Should the spell duration expire while the subject is still aloft, the magic fails slowly. The subject floats downward 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, taking 1d6 points of damage per 10 feet of fall. Since dispelling a spell effectively ends it, the subject also descends safely in this way if the fly spell is dispelled, but not if it is negated by an antimagic field.
See Falling Damage if something bad happens!
When a character or creature is flying, and that creature decides to ascend at a 45 degree angle, the rules states that it moves at half speed? Do the rules for diagonal square counting still apply when moving up diagonally in this way?
No. Since the game is generally assumed to be played in two dimensions, even when representing three dimensional combat, the rules for ascending are handled by the speed reduction instead of asking players and GMs to ascertain the diagonal vertical movement.
