Materialist, an early-to-mid-game Mending Side-grade

When an item has the Materialist enchantment, it can be repaired in an anvil with that item's "repair material" as many times as the player wants to do so, without the anvil's "too expensive!" being a barrier.

When the player is wearing or holding a Materialist enchanted item, and touches an Experience Orb, that Orb's points are consumed to reduce the item's anvil "Repair Cost."

The amount which the "Repair Cost" is reduced is the number of points in the Orb, divided by the points needed to go from the beginning of the player's current level to the beginning of their next level.

Materialist enchanted items in an inventory display the "Repair Cost" in the lower-left part of the inventory slot, in the same font as normal items have their stack size in the bottom right.

Materialist is next-level incompatible with Mending. An Anvil will refuse to combine a Mending item with a Materialist item, unless both items are Enchanted Books, in which case the items combine but one enchantement or the other is lost.

Materialist Enchanted Books are sold by Librarians, can be made using an Enchanting table, can be gotten by fishing, and can be found in loot chests of Dungeons and Villages.

Mending is still in the game, but Enchanted Books with it are not gotten any of the ways which Materialist books are. Mending books now have a chance to be found in the loot chests of all structures except Dungeons and Villages. They are also now sold by Wandering Traders.
