Infinity

Infinity is a very rare ranged enchantment in Minecraft 1.21. Infinity lets a bow fire ordinary arrows without consuming them, so a single arrow in your inventory becomes an unlimited supply for that bow.

There is only one level to it, so nothing needs upgrading — the instant it goes on your bow you have the whole effect (Regular arrows are not consumed (still need 1 arrow in inventory)).

Infinity exists at a single level only, so there is no scaling curve to climb — applying it to your bow hands you the complete effect in one step, with no Infinity II to chase.

It has just one level and no scaling — you either have endless regular arrows or you do not. The one catch is that it works only with plain arrows; tipped and spectral arrows are still used up normally.

Infinity fits exactly one item — the bow — and nothing else will accept it, so it is a dedicated bow enchantment through and through.

Infinity cannot share a bow with Mending. Because of that single conflict you have to pick either Infinity or Mending for any given bow — never both.

Infinity can be rolled directly at an enchanting table, where reaching its top level of I on a bow generally wants a fully bookshelf-powered table at roughly level 11. Should the table prove stingy with Infinity, you can instead source the book from loot chest and villager trading and anvil it on.

Its selection weight of 1 makes Infinity a very rare roll: it surfaces only now and then on a bow, so you may need to re-roll several times or simply trade a villager for the book.
