Eternals is one of those parts of League of Legends that the game itself introduces and then never revisits.
Short answer
Eternals is a fixed part of League of Legends that most players encounter once and remember, whether or not they understood it at the time.
The game introduces it quickly and assumes you picked it up, which is where the confusion starts. Two similarly named things exist, and mixing them up explains a lot of contradictory advice. Most of the disagreement you will find online is two people describing different builds.
Why people keep asking about it
It appears in supplementary material in more detail than it does in the game. It is more consequential in the late game than the early one, which is why first impressions mislead. Screenshots age faster than text, which is why this describes rather than shows. The wiki entry is thorough and buries the actually useful part six paragraphs down.
Its role has changed across updates, so older discussion describes something slightly different. It helps to understand why a step exists, because then you can adapt it when your situation is slightly different. Whether it is worth going out of your way for depends entirely on how you are playing.
What it is
There is a persistent myth attached to it that has never been true in any version. None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of. Knowing this does not make you better at League of Legends, but it does make the rest of it legible.
- Note where it first appears, so you can go back if you need to.
- It rewards attention rather than preparation.
- Write down what you changed, so you can undo exactly one thing if it goes sideways.
- Treat wiki trivia sections as trivia rather than mechanics.
- Ignore the myth attached to it; it has never held up.
How it connects to the rest of League of Legends
Community shorthand around it has drifted far enough from the original meaning to cause arguments. Where two approaches both work, the one with fewer moving parts is the one to keep. Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. A single check up front replaces a lot of guessing later.
Nothing here assumes a particular playstyle beyond wanting the thing to work. The developers have changed their mind about this at least once, which explains the older advice. What follows assumes you are on a current install and have not modified it.
What it changes in practice
Anything that behaves differently on console than on PC is flagged where it matters. The awkward part is rarely the step itself, it is knowing which step comes first. Do the cheap check before the expensive one — that ordering alone saves most of the frustration.
The community wisdom on this is roughly half right, and the half that is wrong costs the most time. There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing. Everything below is framed around the current state of League of Legends rather than a launch-week impression.
Where you encounter it
The short version is near the top on purpose; the reasoning is there if you want to know why. If you are coming to this after a long break, the terminology has probably moved on. If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about.
Where people go wrong
- Treating a rare edge case as the normal behaviour and planning around it.
- Assuming a guide from an older season still describes the current version.
- Trusting a video thumbnail that promises a result the video never actually shows.
- Ignoring the platform-specific note and then wondering why the steps do not line up.
League FAQ
How long does this take?
Minutes if it goes cleanly, an evening if you hit the edge case in the caveats list. Neither is unusual.
Why do other guides describe this differently?
Most were written for an earlier version and never revisited. Compare the steps against what your build actually shows.
Can I miss it?
Where it is missable, that is noted above. Most players encounter it without going looking for it.
Does this work the same on console and PC?
The logic is identical. Menu paths and button prompts differ, and any real difference is flagged above.
Anything that shifts with the next League of Legends update will show up as a changed number, not a changed approach.
