Effect

Harmonic Echo: When you heal or shield an allied champion, the effect links to the allied champion within 800 units with the lowest percentage Health, and grants them 30% of that heal or 35% of that shield.

If no other allied champion is in range, the original target instead receives that heal or shield.

Only the top core 3-item combinations Tencent publishes are counted, so the pick rate reads lower than actual and win rates and shares lean toward the top. Streamer and pro builds are the 407 Chinese builds published by Tencent (excluding those with removed items). Support items are rarely included, so this reads low.

How it is calculated

Pick rate is the sum over champions and lanes, and win rate is the average weighted by it. The lane breakdown and "Items in the same core" are shares of that sum. Match counts are not published, so every champion is weighted equally.
