Jetpack

The Jetpack is a Hardmode Accessory which functions similarly to Wings. Height-wise, it ranks between Angel/Demon Wings and the more advanced Butterfly Wings. The Jetpack can ascend faster while holding the "up" key - "W" by default. This increased speed can lead to a somewhat higher range, although slightly below Butterfly Wings. This speed boost is excellent for fighting bosses without the use of Gravitation Potions.

While flying, the Jetpack produces nearly the same particle effect as Rocket Boots, which changes to a smaller, stuttering version when gliding.

The Jetpack cannot be crafted. It must be bought from the Steampunker for 40 gold (32 gold using Discount Card). However, the Steampunker only sells them during a waxing moon phase (day or night)so you wont be able to buy it all the time.
