What is the best build for Sion?

We do not publish a best build for Sion, and the reason is worth thirty seconds. The most recorded Sion top build on patch 16.14 is Unending Despair, Hollow Radiance and Jak'Sho, The Protean, in 30 games. A finished item set is read at the end of the game, so a build only appears once the game ran long enough to buy it, and a game that runs long is usually a game you were winning. Any share of wins taken from those games leans high for that reason on its own, which is why there is not one in this answer. The page lists every recorded build with the games behind it.

What are the best runes for Sion?

The most recorded Sion top rune page on patch 16.14 takes Grasp of the Undying out of Resolve, with Demolish, Second Wind and Overgrowth beside it and Biscuit Delivery and Approach Velocity out of Inspiration. Players who ran it won 48.9% of 1,026 games, range 45.9% to 52.0%. A rune page is locked in at champion select, so that share is not inflated by long games the way a build is, but it counts who picked the page rather than what the page did.

Share of those games that were wins, in percent 37% (range 22-54) · 30 games · Measured

Games that finish a build are games that lasted, and lasting usually means winning, so this figure leans high before the items do anything. It is how those games went, not what the build does to your chances. How far that can bend a number.

Sion top is the role with the most recorded games on patch 16.14: 1,469 games, of which 712 were wins. That is the role this page leads with. Measured on this page: top, mid, support, jungle and bot, the roles that cleared 30 recorded games.

wins 0.6 per 100 vs the top average · 1,469 games on 16.14 · first-time players measured (1,396 games) · no clear move vs 16.13 (-4.0, range -16.1 to +8.1)

The build above is the one recorded most often, nothing more. Every recorded build, with its own games and its own share, is in the build list, in the order players built them.

Why this answer

A champion and role pair needs 30 recorded games before we put a score or a win impact on it: under that, a handful of lucky games moves a win rate by ten points. The same floor applies to a single build and to a single rune page, and anything under it prints its games and no number.

The share on that figure says how the games went, not what the build does to you. Nothing on this page measures that; the method note at the end says why.

What do most Sion players build?

Item sets recorded on patch 16.14, most built first, never sorted by how the games went. The share is how many of a build's own games were wins; a build under 30 games shows its games and no share.

A finished set is read at the end of the game, so every share here leans high: games that last long enough to finish a build are usually games that were already going well. How far that can bend a number.

What runes do most Sion players run?

Whole pages that players actually ran, most recorded first. A page is locked in at champion select, so long games do not inflate its share the way they inflate a build's; it still counts who picked the page rather than what the page did.

How we count level-ups

When do players buy each piece?

The pieces of the most recorded Sion top build, in the order players buy them. The time is the middle of the spread across every recorded game on patch 16.14, measured at the buy rather than at the end of the game: half the recorded buys of the item happen before it, half after.

Buy times, earliest first

Hollow Radiance: 13:23 145 games
Unending Despair: 21:11 190 games
Jak'Sho, The Protean: 28:02 261 games

The bar is scaled to the latest piece of the set. Each item links to its own page, where the whole spread sits beside the games behind it.

Why no share of wins on this page says a build is good for Sion

A finished item set is read at the end of the game. A player who bought the first two items and lost at twenty minutes never finished the set, so they are not in its row. Everybody in the row lasted long enough to buy it, and lasting is most of what winning looks like. The share those games won is pushed up by that on its own, before the items do anything at all, and the push is largest on the most expensive builds and backwards on the ones you buy when a game is going badly.

We know the size of it. In simulation, with every item's real effect set to exactly zero, an item read at the end of the game shows about 92% as a sixth completed item. A defensive item with a real 5 point benefit shows about 20 points the wrong way, because it gets bought when a player is behind. The measurement is here.

So this page counts and labels rather than ranks. The estimate that answers the real question is taken at the moment of the buy, from the state the purchase happened in, and it runs in the desktop app because it needs the game in front of it.
