• Galaxite Equipment: Made in the Anvil / Smithing Table by upgrading Diamond Equipment.
  Will have the exact same stats as Diamond Equipment (maybe slightly worse to accustom the abilities?)
• Galaxite Ingot: Made by merging *insert thing like netherrite scrap* and Gilded Chorus Flowers (4 gold ingots + 4 fruits + 1 chorus flower) shapeless (4 flowers and 4 *insert thing like netherrite scrap*)
• Galaxite Blocks: When crouched on for 1 second will let you teleport to the nearest (max 16 blocks) Galaxite Block.
  This allows for simple elevators and warping between different rooms. But it could not easily be used to create long-distance teleporation because of the limited range, and the fact that it will only teleport you to the nearest galaxite block.
• Galaxite Tools: Extended Mining Reach, the End Power in the Galaxite lets you bend spacetime to mine (and attack?) further.
• Galaxite Weapons: Extended Attack Reach (??? subject to change)
• Galaxite Armor: Let teleport you in the direction you're facing after crouching for 2.5/2/1.5/1 second up to 10/20/30/40 blocks away with 1/2/3/4 armor pieces

So I would like to suggest to @[Insane96MCP] some abilities that galaxite could have that would make it more interesting. And would also hopefully be thematic and easy to impliment. Number one is galaxite blocks. Jumping on a galaxite block could teleport entities to the closest galaxite block (within ~16 spaces). This allows for simple elevators, warping between different rooms, and more easily moving mobs into a specific location. But it could not easily be used to create long-distance teleporation because of the limited range, and the fact that it will only teleport you to the nearest galaxite block
Galaxite tools could have an extended reach, inspired by the enderman's long arms. Or say it's because the teleporting power of the end lets you bend spacetime to mine blocks that are a little further away than usual. Alternatively (or in addition), mining a block with a galaxite tool while holding shift sends that block directly into your ender chest. Or simply make their speed buff apply in all dimensions. I mean, what can you even use a shovel for in the end? Swords could send mob drops to an ender chest, have longer attack/sweep range, or knockback/warp hit mobs away from you.
A full set of galaxite armor means you'll only lose an average of 4 stacks of items each time you fall into the void. However, you're probably not going to wear a full set of galaxite armor. An elytra is way better to avoid the void, and the player gets access to elytra and galaxite at the same time. I'm assuming missing the chest piece lowers the per-slot keep item chance from 90% to around 75%, which means that with a full inventory, falling into the void means you lose an average of 9-10 stacks. About a quarter of it. That's not nothing, but it doesn't seem strong enough to make up for the fact that this super-late game armor is worse than iron.
Some additional options or alternatives: an elytra can be added to the galaxite chestplate (or is required to craft it). It would grant the powers of the elytra, plus the damage reduction and void item loss of the armor. That removes the opportunity cost between galaxite and elytra, but diamond is still useful in cases where you need maximum armor. wearing galaxite armor could send your inventory to your enderchest whenever you die (or at least when you fall in the void?). It could reduce (and negate with a full set) the damage taken from using ender pearls. And/or wearing galaxite armor gives you a chance to not consume ender pearls when you throw them, essentially letting you teleport for free some percentage of the time.
