Angel Wings

The Angel Wings are a new accessory which allows flight, much like Rocket and Spectre Boots. They can be compared with the Demon 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 and it is possible to hit the skybox (and cause Wyverns to appear) on a small world. Also, while in flight, the movement speed bonus of Hermes and Spectre Boots is in effect as if you were on the ground. They also stack with Shiny Red Balloon and Cloud in a Balloon for increased base flight time, similar to how the balloon affects jump height. Combine Angel/Demon Wings, Spectre Boots, and Cloud in a balloon to amazing effect.

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

Effective strategies
If the player has an Ice Rod they can use this to shoot blocks of ice under themselves and land in mid air this means you can stay in the air almost indefinatly as long as you have enough mana.
