Channeling

Channeling is a very rare ranged enchantment in Minecraft 1.21. Channeling calls down a lightning bolt onto any mob your thrown trident hits, but only during a thunderstorm and only if the target is exposed to the open sky.

There is only one level to it, so nothing needs upgrading — the instant it goes on your trident you have the whole effect (Summons lightning on hit during thunderstorms).

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

It has a single level with no scaling. When the conditions line up, the strike can do dramatic things: it turns creepers into charged creepers, villagers into witches, pigs into zombified piglins and toggles a mooshroom's colour.

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

Channeling cannot share a trident with Riptide. Because of that single conflict you have to pick either Channeling or Riptide for any given trident — never both.

Channeling can be rolled directly at an enchanting table, where reaching its top level of I on a trident generally wants a fully bookshelf-powered table at roughly level 5. When the enchanting table refuses to offer Channeling, the same enchantment is available as a book from loot chest and villager trading for anvil application.

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