XP Crystals (XP Storage & More)

The XP Crystal is a new crystal that wouldn't come in the form of geodes.

They share the same color pallette as the XP orb and they grow on ceilings of caves.

The player can mine the XP Crystal to get a good amount of XP based on the growth stage of the crystal.

The XP Crystal has a total of 4 growth stages, and each growth stage gives the player an additional XP level when mined. (Stage 1 = 1 level, Stage 2 = 2 levels, etc.)

These crystals grow in levels Y: 30 and lower, and they are not common.

XP Crystals can be mined with a stone pickaxe and higher.

The player can get the actual crystal using a silk touch pickaxe, but the crystal can't be placed down.

Using the XP Crystal from a silk touch pickaxe, you can turn it into a Bottle O' Enchanting that contains the amount of XP levels the crystal has with it's growth stage.

This would be a fun way to award players that venture in the deep caves and would make for a fun experience for adventurers, and also gives way for XP storage.
