Rules of Flight

Flying in light armor requires a Strength score of 11 or higher.
Flying in medium armor requires a Strength score of 13 or higher.
Flying in heavy armor requires a Strength score of 17 or higher.
If your Strength score is less than 13, you have disadvantage on weapon attacks with weapons that lack the light property while flying.
If your Strength score is less than 17, you have disadvantage on weapon attacks with weapons that have the heavy property while flying.

You can start flying if you are in an open space at least one size larger than yourself, and you are not prone, restrained, or incapacitated.
While flying, if you aren't incapacitated or restrained, you gain the following benefits:
- You can move in any direction.
- You can start gliding on your turn (no action required).
- You gain a +2 bonus to Dexterity saving throws.

While flying or gliding, if you are prone or restrained (and you cannot hover), or if you are incapacitated at the end of your turn, you start falling (unless something else is keeping you aloft).
While falling, you fall 500 feet at the start of each of your turns. Unless it is your first round falling, you also fall 500 feet at the end of each of your turns.
If you aren't restrained or incapacitated, you can use your reaction while falling to start gliding.

During each of your turns while gliding, you descend a number of feet equal to twice your flying speed, spending 5 feet of movement for every 10 feet you descend.
While gliding, you can move up to 20 feet horizontally for every 10 feet you descend.
If you take the Dash action, you descend an additional number of feet equal to twice your flying speed.
You take no fall damage if you land while gliding.
On your turn, you can spend movement equal to half your flying speed to stop gliding and start flying normally.
- Once you do this a number of times equal to your Dexterity modifier (minimum of once), you cannot do so again until you spend 1 minute without using your flying speed.
If you can hover, you cannot glide.

If you have a racial flying speed, and you aren't 5th level or higher, you fall prone if you end your turn in the air and aren't gliding. This replaces any racial limitations on flight.
You can fly a number of hours equal to your Constitution modifier (minimum of 1 hour) in one day. For each hour you spend flying past this number, you must succeed on a Constitution saving throw or suffer 1 level of exhaustion. The DC of this saving throw is equal to 10 + the number of additional hours traveled.
If you are carrying weight over 5 times your Strength score while flying, and aren't gliding, then you must make a DC 10 Strength (Athletics) check at the end of each of your turns. On a failure, you begin falling, unless you immediately let go of the weight.
