Rush

-Leaf Charm:
An early game item that allows the player to launch themselves up a few blocks. If timed right, it can even negate fall damage!

-Soul Diffuser:
An item that makes the player invisible, gives them a lot of resistance and lets them move really fast for a short blink. It's designed to be used without armor on -so the invisibility isn't useless-, but it can also be used with armor.

-Flash Shard:
A late game item that instantly blinks the player about 15 blocks in the direction they are facing. This can get you stuck inside solid blocks though, so use it with caution!

-Bedrock Splitter:
A late game item that allows you to break one block instantly, giving you the item you broke. As the name suggests, this even works on bedrock!

-Unbreaking Charm:
A late game item that lets you make one item of your choice unbreakable. It can only be crafted using bedrock though, so you'll need to have obtained a bedrock splitter before an ubreaking charm.

-Gem of Repairing:
A mid game item that can be used to repair your tools without any penalties on the tool.

-Fight Picker:
Originally a seperate mod, this battle pickaxe will let you fling your enemies -and yourself- across the battlefield. If not clear enough already, it can also be used as a pickaxe!
