Item Effects
- 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, excluding yourself, 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 same extra heal or shield.

- When you heal or shield an allied champion, the effect links to the nearest allied champion within range with the lowest percentage Health, excluding yourself, 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 same extra heal or shield.
Our take
300 gold cheaper, with 100 more Health and 5 more Ability Haste. Max Mana and Heal and Shield Power are gone.

Our take
Harmonic Echo costs 200 more while both the echoed multiplier and the base restore come down. A single proc no longer swings a teamfight as far, so spamming heals recovers less ground than it used to. Ability haste rises to +15 in exchange, keeping the number of procs intact. The item supports through repetition now rather than through raw healing.
Harmonic Echo
Patch 7.1bBase Stats
- Mana Regen+0 → +50%
Our take
Harmonic Echo gains 50% mana regeneration. The item rewards continuous healing and support, which is exactly what drains mana fastest, so better regeneration lets its owner keep doing that job. During stretches where fights come back to back, there is less need to hold abilities in reserve. Several support items received the same treatment this patch, so support players get noticeably more breathing room overall.
