You can fly with medium or heavy armour on.

- In order to fly wearing medium armour, you must first make a strength check of your AC bonus given by your armour, minus your Dexterity modifier or higher to take off. (E.g. If you are wearing hide and had a Dexterity modifier of +3. 12 (The bonus given by your armour) - 3 (Your dexterity modifier) = 9, so you'd have to make a strength check with a DC of 9.) On a successful check, you may take flight as per normal. On a failed check, you do not take flight.

- In order to fly wearing heavy armour, you must first make a strength check of your AC bonus given by your armour. (E.g. If you are wearing chainmail. The bonus given to your AC by Chainmail is 15, so you'd have to make a strength check with a DC of 15.) On a successful check, you may take flight as per normal. On a failed check, you do not take flight.

If you end your turn aloft, you must also make the strength checks pictured. On a successful check, you remain aloft. On a failed check, you fall from the air and take appropriate fall damage.
