So, if she weighs the same as a duck...

So, if a witch takes the Flight hex, the following applies:

The witch grows lighter as she gains power, eventually gaining the ability to fly.

So - how much does a witch with the flight hex weigh?

At 1st level? (feather fall at will and +4 swim check)

At 3rd level? (levitate once/day)

At 5th level? (fly level minutes/day)

Beyond?

She has the same mass and density but magic counteracts gravity to make her lighter.

maybe you should give her damage reduction 5/slashing to represent her being made of wood. then, when you need to cross a river you can build a bridge out of her...

Not necessary. Witches float 100% of the time, it's how they find a coven.
