Demon Wings

The Demon Wings are a new accessory which allows flight, much like Rocket Boots. They can be compared with the Angel Wings. After having spent the flight time, continuing to hold the jump key causes slowfall.

This stacks with Rocket Boots and Spectre Boots. No animation is shown by the boots, but flight time is increased. With both Demon Wings/Angel Wings and Rocket Boots/Spectre Boots, the player can achieve a flight time of roughly 5 seconds.

Demon Wings also seem to normally act as the Lucky or Obsidian Horseshoe in that fall damage is negated.
