Win with
context.

Goldiff is a League build lab for people who want more than win-rate bait. We read item order, rune pages, shards, boots, and spell pairs through contextual MWPA — so the site tells you what actually held up, not just what showed up in already-winning games.

02 · Manifesto

Win-rate bait is not a build path.

An item can post a 58% win rate and still be a trap because it only gets bought in games that are already won. Goldiff filters that noise by comparing every build choice against a contextual baseline — not the global average.

03What it reads3 SIGNALS · CONTEXTUAL

Ordered itemsI

Path scoring stays slot-aware.

A third-item read only compares against games that reached a third item. We stop rewarding late purchases just because those games were already winning.

Rune pagesII

Read as a page, not a keystone.

Primary tree, secondary path, and shards are sampled together so the rune read still reflects real pages people actually ran.

Role hygieneIII

Flex picks visible without noise.

Meaningless edge roles are filtered out, but champions with real off-role usage still surface when the sample actually supports it.

04Scoring flow3 STEPS · MWPA

A product-shaped
way to explain
the math.

Three checkpoints, one composite read. We don't pretend a single stat explains an entire match — but we won't bury you in academic notation either.

Full methodology

Anchor the baseline

Start from the champion's own sample, so Ahri mid is not graded against random support fragments.

Follow the order

Item paths evaluated as first/second/third checkpoints. Order matters because timing changes signal.

Stack the page

Runes, shards, boots, and spell pairs add directional context on top of the item path.

05Boris checkPERSONALITY · OPT-IN

“Don't let Boris cook.”

One page to test item order, full rune pages, shards, boots, and spells — before Boris talks you into something cursed. The composite signal tells you whether your loadout outperformed the champion's contextual baseline, or whether you just got talked into a pretty tooltip.
