It shares the <strong>LIFELINE item group<\/strong> with Sterak&#8217;s Gage, Immortal Shieldbow, and Maw of Malmortius \u2014 all of which provide below-30%-HP emergency survival passives. Only one LIFELINE item can be held at a time.<\/p>\n\n\n\n<p>What distinguishes Protoplasm Harness from other LIFELINE items is its <strong>heal scaling with both bonus armor and bonus magic resistance<\/strong>. At 175% bonus armor + 175% bonus MR scaling, the heal value grows proportionally with every defensive item built. A tank with 200 bonus armor and 150 bonus MR at full build receives a LIFELINE heal that is significantly larger than the item&#8217;s base level-scaling heal \u2014 making Protoplasm Harness <strong>the LIFELINE item specifically designed for tanks who stack both armor and MR<\/strong><\/p>\n\n\n\n<p>At <strong>2,500 Gold<\/strong>, it is the most affordable LIFELINE item, sitting below Sterak&#8217;s Gage (3,000g) and Immortal Shieldbow (3,000g).

At full tank Malphite, 200+ bonus armor and 100+ bonus MR triggers a LIFELINE heal exceeding 800+ HP over 5 seconds. The 25% tenacity during the LIFELINE window also reduces the duration of any CC landing on him at low HP.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/en\/wiki\/amumu-the-sad-mummy\/\">Amumu<\/a> \u2014 <\/strong>He naturally builds mixed armor and MR as a tanky jungler. His full build (Sunfire + Abyssal Mask + Warmog&#8217;s + Force of Nature) provides substantial bonus armor and MR. The 10% movement speed during LIFELINE helps him escape after an engage that took him low, and 25% tenacity reduces enemy chains as he tries to disengage.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/wiki\/leona-the-radiant-dawn\/\">Leona<\/a> \u2014 <\/strong>Her W Eclipse provides a passive armor and MR buff during sustained combat. Her full engage build includes both armor (Sunfire, Randuin&#8217;s) and MR (Force of Nature, Abyssal) items. The LIFELINE heal at 30% HP after a deep engage dive gives her a survival window to either escape or continue fighting while healed.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/wiki\/ornn-the-fire-below-the-mountain\/\">Ornn<\/a> \u2014 <\/strong>His passive Living Forge gives bonus armor and MR from items beyond 1,300g HP items. He naturally reaches high bonus armor and MR through his full tank build. Protoplasm Harness&#8217;s LIFELINE scales directly with these stats \u2014 and the 15% size increase during LIFELINE visually signals to the team that he&#8217;s activating a survival window.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/wiki\/nautilus-the-titan-of-the-depths\/\">Nautilus<\/a> \u2014 <\/strong>His engage style (Q hook + R engage) frequently puts him at burst risk from enemy carries after engaging. LIFELINE at 30% HP gives him a second window after taking the initial burst to continue CCing with his E and W. The tenacity helps resist chains when low.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/wiki\/shen-the-eye-of-twilight\/\">Shen<\/a> \u2014 <\/strong>His Spirit&#8217;s Refuge (W) provides defensive utility that works alongside LIFELINE&#8217;s survival window. At full tank Shen (often with both armor and MR), the LIFELINE heal provides significant HP recovery after taking dive damage. The 10% movement speed also complements his already-mobile Split Push pattern for escaping after an engage.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>\u274c Suboptimal Picks<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>AD fighters and bruisers: <\/strong>Sterak&#8217;s Gage is almost always better for bruisers \u2014 it scales with bonus HP and base AD, matching their stat profile.

How to Avoid Them<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Building only armor or only MR \u2014 underutilizing one scaling component: <\/strong>Protoplasm Harness heals for 175% bonus armor AND 175% bonus MR. A build with 300 bonus armor but only 50 bonus MR contributes 525 HP from armor but only 87.5 HP from MR \u2014 leaving the MR scaling almost entirely unused. Balance the armor\/MR investment to maximize both scaling contributions.<\/li>\n\n\n\n<li><strong>Picking Protoplasm Harness on AD fighters instead of Sterak&#8217;s Gage: <\/strong>Sterak&#8217;s Gage scales with bonus HP and base AD \u2014 much better for AD bruisers. Protoplasm Harness&#8217;s value requires building defensive items that AD fighters don&#8217;t typically prioritize. On Darius or Garen, Sterak&#8217;s LIFELINE is stronger; on Malphite or Ornn, Protoplasm Harness is stronger.<\/li>\n\n\n\n<li><strong>Misunderstanding LIFELINE as an instant heal: <\/strong>LIFELINE&#8217;s heal is a heal OVER TIME distributed across 5 seconds \u2014 not an instant burst heal. This means if the tank is killed immediately after LIFELINE triggers, the heal doesn&#8217;t fully complete. The bonus health (200-311 HP) is the immediate buffer; the heal provides sustained recovery. Position to survive past the trigger, not to rely on the heal to instantly restore HP.<\/li>\n\n\n\n<li><strong>Holding both components without completing through an objective fight: <\/strong>Kindlegem&#8217;s 10 AH is significant for engage tanks during fights. Completing Protoplasm Harness before Baron or Dragon control fights ensures the full 20 AH and 600 HP are active, not just the component stats.<\/li>\n\n\n\n<li><strong>Not coordinating with teammates during the LIFELINE window: <\/strong>The 15% size increase is visible to both teams \u2014 enemies know LIFELINE is active and may disengage. Communicate the 5-second survival window to allies so they can follow up during it. The 25% tenacity during this window is most valuable when enemies are actively CCing \u2014 having allies apply pressure forces enemies to choose between focusing the surviving tank or switching targets.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\u2705 Best Practices<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Stack both armor and MR: <\/strong>Sunfire\/Randuin&#8217;s\/Thornmail for armor + Force of Nature\/Abyssal Mask\/Hollow Radiance for MR; both 175% components contribute simultaneously<\/li>\n\n\n\n<li><strong>Use the LIFELINE window aggressively: <\/strong>5 seconds of 10% bonus movement speed + 25% tenacity + sustained heal is a second fight window \u2014 don&#8217;t retreat immediately after triggering; the heal may sustain through the enemy&#8217;s follow-up burst<\/li>\n\n\n\n<li>Pair with Warmog&#8217;s Armor for between-fight regen: Protoplasm Harness&#8217;s 600 HP + Warmog&#8217;s 800 HP exceeds the 3,000 HP threshold for Warmog&#8217;s passive regen \u2014 fully healing between fights compounds the LIFELINE&#8217;s in-fight survival<\/li>\n\n\n\n<li><strong>On Ornn: <\/strong>his passive Living Forge grants additional resistances from HP items \u2014 every tank item he builds toward LIFELINE scaling also feeds his passive stat bonuses; the compounding is disproportionate<\/li>\n\n\n\n<li>Communicate LIFELINE activation with team \u2014 the 15% size indicator tells allies the tank has a 5-second survival window and follow-up will be effective<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQ<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: What triggers LIFELINE and when does it activate?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: LIFELINE activates when incoming damage would reduce your HP below 30% of maximum health. It does not trigger when you&#8217;re already below 30% \u2014 it specifically fires on the hit that would cross the 30% threshold. After triggering, an internal cooldown prevents immediate re-triggering. The passive then activates all five effects simultaneously: bonus health, heal over time, size increase, movement speed, and tenacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Is the LIFELINE heal instant or over time?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: The LIFELINE heal is a heal over time distributed over 5 seconds \u2014 not an instant burst heal. The 200-311 bonus health (based on level) provides immediate HP padding, while the main heal (200-423 base + 175% armor + 175% MR) is applied gradually across the 5-second duration. Surviving past the initial trigger is critical to receiving the full heal value.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Why does Protoplasm Harness scale with both armor and magic resistance?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: The dual scaling design positions it as the tank-specific LIFELINE item. Unlike Sterak&#8217;s (AD-oriented) or Immortal Shieldbow (ADC-oriented), Protoplasm Harness explicitly rewards champions who stack both defensive stats \u2014 full tanks who build armor AND MR items. The 175% scaling from both stats means a fully-built tank with 200 bonus armor and 150 bonus MR receives over 1,000 HP of healing over 5 seconds, which no other LIFELINE variant approaches for that build profile.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Can I hold Protoplasm Harness and Sterak&#8217;s Gage simultaneously?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: No. Protoplasm Harness, Sterak&#8217;s Gage, Immortal Shieldbow, and Maw of Malmortius all share the LIFELINE item group. Only one can be held at a time \u2014 the shop prevents purchasing a second LIFELINE item while one is already in the inventory.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Does the 25% tenacity during LIFELINE stack with other tenacity sources?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: Tenacity sources apply multiplicatively rather than additively. If you already have 20% tenacity from runes or items, adding 25% from LIFELINE results in combined tenacity of approximately 40% (1 &#8211; 0.80 \u00d7 0.75 = 0.40), not 45%. The tenacity is most impactful when it&#8217;s the primary or only tenacity source active \u2014 providing maximum CC duration reduction during the 5-second survival window.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Is Protoplasm Harness better on tanks or bruisers?<\/strong><\/h3>\n\n\n\n<p><strong>A: <\/strong>A: Tanks \u2014 specifically full tanks who build both armor and MR items. The 175% bonus armor + 175% bonus MR scaling is designed for champions who stack defensive stats, and full tanks at levels 16-18 with complete armor\/MR builds can generate 900-1,300 HP of LIFELINE healing. Bruisers who primarily build HP and AD (Darius, Garen, Camille) should use Sterak&#8217;s Gage \u2014 its bonus HP and base AD scaling matches their stat profile.<\/p>\n","protected":false},"featured_media":14313,"comment_status":"open","ping_status":"closed","template":"","class_list":["post-17555","wiki","type-wiki","status-publish","has-post-thumbnail","hentry","wiki-category-items-lol-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Protoplasm Harness - MagicStark<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/magicstark.cz\/en\/wiki\/protoplasm-harness\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Protoplasm Harness - MagicStark\" \/>\n<meta property=\"og:description\" content=\"What is Protoplasm Harness? \ud83e\uddec Protoplasm Harness is a legendary Tank item in League of Legends, categorized under Tank, Health &amp; Regeneration, and Ability Haste.
