Void Mushroom

           A new mushroom-type item for the new End Update, if and when it happens. The mushroom will spawn in a new biome located in the End Dimension, with a very low percentage chance to generate amongst the terrain. The void mushroom is short, stubby, and spiky, with a black texture and purple accent markings. The void mushroom can only be collected with shears enchanted with Silk Touch and can only be placed on End Stone in a low light level.

          Bonemeal cannot speed up the growth rate of the void mushroom, even with its very slow growth rate. The only item that can enable the growth rate of the void mushroom is by placing Wither Roses within 8 blocks. The full-size version is 4 blocks tall, and an Axe with the Fortune enchantment is the only way to get more void mushrooms. Breaking the full-size block with anything other than a Diamond/Netherite Axe with Fortune will drop 0 in return. Drop Rates: Unenchanted (0), Fortune 1 (0-1), Fortune 2 (0-2), Fortune 3 (1-3).

The Void Mushroom can be used to make a potion of Void Walker that allows the brief ability to walk across the void (0:08), w/ Redstone (0:15), along with an additional side effect of Weakness 3 & Blindness (1:00), w/ Redstone (3:00). Cannot be made into a Splash potion or Lingering potion.

It's more rudimentary than what enables the Endships to fly but still effective.
