Boots of Flight

Adds an item that allows you to fly around. The chest is at the starting location, in the Spawning Meadows. Meant either for the platforming-impaired or to mess around. Notes: If you fly up high enough, fog will ruin your visibility. While you can mod the fog away if you wish, then you will run into issues with distant terrain not being loaded.

Warning: your character will seem stuck after resting at an inn while flying. Either hold the jump button or remove the boots and you'll be able to move again.

For modders, you might want to use Debug Kit instead, which also includes a flying mount on top of the rest of their functionality:
