User:Aeldrion/Projects/CVM/Rocket boots module

The Rocket boots module adds the ability to turn any pair of boots into a pair of rocket boots that grant players with the ability to fly.

Crafting
Any boots can be turned into rocket boots with fireworks in a Celestial compendium.

Usage
When a player wearing rocket boots sneaks, they will be propelled upwards and start to levitate, as long as they keep pressing the sneak key. When the player takes off when standing on any solid block, fire will be placed. This can be avoided by using rocket boots while jumping or falling.

Renaming mobs
Non-boss mobs can be renamed Yolo to start levitating and making particles for a random duration as if they were using rocket boots. Since the flying effect grants no fall resistance, this can be used to let mobs drop to their own death, although it requires name tags.
