Protoplasm Harness — the Lifeline Health Item

2,600gold

Protoplasm Harness was nerfed in patch 26.14: the price rose from 2,500 to 2,600 gold, and Lifeline's lowest bonus Health and healing both dropped to 100. Lifeline fires when damage would take you under 30% Health — extra maximum Health for 5 seconds, healing over that time, 10% Move Speed and 25% Tenacity. Sterak's Gage answers the same threshold with a decaying Shield. Supports took 73.0%.

  • 600 Health
  • 20 Ability Haste

Passive

  • Lifeline: (0s)Taking damage that would reduce your Health below 30% causes you to gain maximum Health for 5 seconds, then heal Health over the duration. While regenerating Health, you gain 15% increased Size, 10% Move Speed, and 25% Tenacity.

Protoplasm Harness balance history

Riot's notes from patch 25.S1.1 to 26.20 change Protoplasm Harness in 2 patches. The latest is patch 26.14, published 2026-07-14.

  1. Patch 26.142026-07-14

    • Cost2500to2600
    • Bonus Health200 - 300to100 - 300
    • Healing200 - 400to100 - 400
    Why, in Riot's words

    Protoplasm is overperforming across the board and is leading to particularly potent spikes on champions that buy it early. We still want to make sure it's still an exciting option for tank champs, so we're focusing on decreasing its early single item spike power.

  2. Patch 26.32026-02-03

    • Lifeline max health gain200to200-300 (based on level)
    • Lifeline healing200-400 (based on level) (+ 250% Armor) (+ 250% Magic Resistance)to200-400 (based on level)(+ 175% Armor) (+ 175% Magic Resistance)
    • Ability Haste15to20
    Why, in Riot's words

    The current shape of this Lifeline effect ended up being a bit too sharp, where it's extraordinarily powerful for the users that can leverage the resistance scaling and somewhat unexciting for most other potential users. We're shifting some power around to make the item more consistently useful and less eye-popping in the outlier cases.
