What is Knight’s Vow? \ud83d\udee1\ufe0f<\/strong><\/h2>\n\n\n\n

Knight’s Vow is the dedicated single-target carry protection item for tanks and engage supports<\/strong>. Unlike Locket of the Iron Solari<\/strong><\/a>‘s teamwide DEVOTION shield, Knight’s Vow focuses all its defensive benefit on one designated Worthy ally<\/strong> \u2014 permanently redirecting 12% of all pre-mitigation physical and magic damage they receive to the Knight’s Vow holder, while the holder heals back from the Worthy ally’s combat damage output. Two champions become a combat unit: one deals damage, the other absorbs a portion of the incoming punishment and recovers HP from the attacker’s performance.<\/p>\n\n\n\n

The SACRIFICE passive operates continuously<\/strong> while the tether is active and the holder is above 30% maximum health \u2014 it requires no button presses, no timing, and no reaction. The 12% damage redirection is pre-mitigation, meaning it bypasses the Worthy ally’s armor and MR reductions and arrives at the holder where it is then reduced by the holder’s own defensive stats. A tank support with 200 armor redirecting 12% of an ADC’s physical damage intake effectively converts 12% of incoming burst into reduced physical damage filtered through their higher armor value.<\/p>\n\n\n\n

At 2,300 Gold<\/strong>, Knight’s Vow provides a practical defensive stat package for tanks: +40 armor, +200 HP, +10 AH, and +100% base HP regen. Building from Kindlegem<\/strong><\/a>, Chain Vest<\/strong><\/a>, and Rejuvenation Bead<\/strong><\/a> with a 400g combine. Sell price: 1,610 Gold<\/strong>. ID: 3109.<\/p>\n\n\n\n

\ud83d\udcca SACRIFICE \u2014 Damage Redirect Math<\/strong>12% pre-mitigation redirect: the 12% is taken from the Worthy ally’s raw incoming damage BEFORE their armor\/MR reduce it.Example: ADC takes a 500 damage physical hit (pre-mitigation).  SACRIFICE redirects 12% of 500 = 60 raw physical damage to the Knight’s Vow holder.  ADC’s armor (e.g., 50 armor) reduces the remaining 88% = 440 damage \u2192 440 \/ 1.50 = 293 effective damage to ADC.  Knight’s Vow holder’s armor (e.g., 200 armor from full tank build) reduces the redirected 60 damage \u2192 60 \/ 3.00 = 20 effective damage to holder.  Total effective damage to the duo: 293 (ADC) + 20 (holder) = 313 vs 333 without Knight’s Vow. Net 20 damage saved \u2014 the tank’s higher armor makes the redirected portion far more efficient.Heal mechanic: holder heals 10% of post-mitigation damage dealt by Worthy ally to champions. At 500 DPS ADC (post-mitigation to enemy champion): holder heals 50 HP per second while ADC attacks. In a 10-second sustained fight: 500 HP healing to the tank from the ADC’s DPS output.30% HP threshold: SACRIFICE stops redirecting if the holder drops to or below 30% max HP. A 2,000 HP tank: redirection active above 600 HP, inactive at or below 600 HP. This prevents Knight’s Vow from killing the holder through their own protective damage absorption.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83d\udca1 Chain Vest \u2014 Armor-Heavy Mid-Item Path<\/strong>Chain Vest<\/strong><\/a> (800g) provides +40 armor immediately at component level \u2014 highly impactful against ADC-heavy bot lane matchups where the armor directly reduces physical damage from the enemy carry. Purchasing Chain Vest first back establishes early armor before SACRIFICE’s 12% redirect is active, enabling the tank support to survive the lane phase more effectively.Rejuvenation Bead<\/strong><\/a> (300g) is the cheapest component \u2014 provides +75% base HP regen at the component level. For supports and tanks with low base HP regen, this translates to approximately 3-5 HP\/5 seconds in base form, enough to sustain minor chip damage between fights. The bead’s cheap cost makes it a natural addition to first or second back purchases alongside Kindlegem or Chain Vest.Recommended sequence: Chain Vest first back (800g, for immediate armor + component stat) \u2192 Kindlegem second back (~800g, HP + AH) \u2192 Rejuvenation Bead + 400g combine. Full Knight’s Vow achievable by 12-15 minutes for efficient supports.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\u2694\ufe0f PLEDGE & SACRIFICE \u2014 Complete Mechanics Reference<\/strong><\/h2>\n\n\n\n

PLEDGE Active \u2014 How to Designate a Worthy Ally<\/strong><\/h3>\n\n\n\n

PLEDGE is a unit-targeted active<\/strong> \u2014 you click on a specific allied champion to designate them as Worthy. The 1,250-unit cast range is generous for a support item, enabling the PLEDGE to be applied from a distance rather than requiring the support to close to melee range. At activation, a visual tether appears between the Knight’s Vow holder and the Worthy ally.<\/p>\n\n\n\n

PLEDGE has no cast time<\/strong>, meaning it can be activated during other ability casts or movements without interrupting them. The activation does not break stealth<\/strong> \u2014 a stealthed support (Twitch<\/strong><\/a> or a champion using Warding Totem<\/strong><\/a>-related stealth) can safely designate a Worthy ally without being revealed.<\/p>\n\n\n\n

Two important restrictions: a champion can only be Worthy to one Knight’s Vow at a time<\/strong> \u2014 if two supports run Knight’s Vow and both try to designate the same ADC, only the first one’s PLEDGE is active; the second PLEDGE targeting the same champion triggers the 10-second static CD<\/strong> rather than reassigning Worthy status. Additionally, you cannot be designated Worthy by an ally’s Knight’s Vow<\/strong> \u2014 the item is always the support protecting an ally, never the reverse where the carry protects the support.<\/p>\n\n\n\n

SACRIFICE Passive \u2014 Continuous Damage Redirection<\/strong><\/h3>\n\n\n\n

SACRIFICE is entirely passive and continuous<\/strong> \u2014 no button presses, no reactions needed. While the tether is active (PLEDGE designated a Worthy ally) and the Knight’s Vow holder is above 30% maximum health, 12% of all pre-mitigation physical and magic damage the Worthy ally takes is redirected to the holder<\/strong> as the corresponding damage type. Physical damage redirected stays physical; magic damage redirected stays magic. Crucially, the redirected damage is then reduced by the holder’s own armor and MR respectively.<\/p>\n\n\n\n

The 30% HP threshold is a hard cutoff<\/strong>: the moment the holder drops to or below 30% maximum health, SACRIFICE immediately deactivates. This is a safety mechanism preventing Knight’s Vow from draining the holder to death in scenarios where the Worthy ally receives extreme burst damage. The threshold means that in situations where the holder is critically low on HP, the passive stops and the Worthy ally absorbs their full damage intake without the 12% redirect.<\/p>\n\n\n\n

The heal mechanic (10% of post-mitigation damage dealt by Worthy ally)<\/strong> creates a sustained self-healing effect on the holder proportional to the Worthy ally’s damage output against enemy champions. A high-DPS ADC dealing 600 DPS (post-mitigation) to an enemy champion generates 60 HP\/second healing for the Knight’s Vow holder. This heal is most impactful in extended sustained fights \u2014 it provides marginal value in all-in burst engagements but compounds meaningfully over 10-20 second fights.<\/p>\n\n\n\n

\u26a0\ufe0f PLEDGE & SACRIFICE \u2014 Critical Rules<\/strong>SACRIFICE redirects 12% of PRE-MITIGATION damage \u2014 the redirect takes from raw damage before the Worthy ally’s armor\/MR reduce it. The holder’s own defenses then reduce the redirected portion.30% HP threshold is a HARD CUTOFF \u2014 drop to 30% max HP or below and SACRIFICE completely deactivates. The holder takes no redirected damage in this state, providing safety against self-death from the passive.One Worthy per Knight’s Vow holder at a time \u2014 retargeting to a different ally costs the 60-second full CD. Targeting an ally who already has Worthy from another Knight’s Vow triggers only the 10-second static CD.You CANNOT be Worthy to your own ally’s Knight’s Vow \u2014 the passive protection is always in one direction: holder protects the ally, never the reverse.SACRIFICE heal is passive and continuous \u2014 no activation needed. The 10% heal from Worthy ally’s damage output scales with the ADC’s DPS against enemy champions.PLEDGE no cast time and stealth-safe \u2014 activate during engage animations, mid-ability casts, or while stealthed without interruption or reveal.Arena: SACRIFICE heal is specifically excluded from triggering Puppeteer’s Pull Their String cooldown reduction augment.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
\ud83d\udca1 Knight’s Vow vs Locket of the Iron Solari \u2014 Single Target vs Teamwide Protection<\/strong>Knight’s Vow<\/strong><\/a>: SACRIFICE \u2014 continuous passive 12% damage redirection to one Worthy ally; holder heals from Worthy’s DPS; no button press; works across the entire fight.Locket of the Iron Solari<\/strong><\/a>: DEVOTION active \u2014 teamwide shield for 200-360 per ally within 850 units; 90s CD; 2.5s decay window; single burst-protection activation.Knight’s Vow: better when protecting a specific high-value target (ADC, fed mid) continuously throughout the game. SACRIFICE is always on \u2014 it doesn’t require timing or CD management.Locket: better when the team needs simultaneous burst protection for all 5 players against a global or AoE threat (Karthus R, Orianna R). One activation protects 5 targets at once.Can both be built? Yes \u2014 many tank supports run Knight’s Vow + Locket of the Iron Solari as items 1 and 2. The two items are not in the same group and stack independently: SACRIFICE redirects damage continuously on the Worthy carry, while DEVOTION provides the emergency teamwide panic button for specific fight moments.Priority decision: if one carry is the primary win condition (hyper-carry ADC or fed mid), Knight’s Vow first. If the team’s win condition requires multiple champions to survive simultaneously (multi-tank engage comp, teamfight composition), Locket first.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83d\udca1 Arena Knight’s Vow \u2014 Heavier Stats, No HP Regen<\/strong>HP 200\u2192400: doubled base HP \u2014 Knight’s Vow becomes a substantial HP item in Arena, providing meaningful bulk beyond just the passive protection.Armor 40\u219250: +10 armor increase \u2014 further improves the holder’s effective HP against physical damage, amplifying the value of SACRIFICE’s physical damage redirect.AH 10\u219215: minor ability haste increase \u2014 slightly faster PLEDGE re-designation after a 60s CD.Base HP regen 100%\u21920%: the regen component is entirely removed in Arena. The item’s sustain value shifts entirely to SACRIFICE’s 10% heal from carry DPS rather than passive regen.SACRIFICE Arena exception: the 10% heal is specifically excluded from triggering Puppeteer’s Pull Their String cooldown reduction augment. This prevents SACRIFICE’s constant healing pulses from creating an infinite CDR loop with that specific Arena augment.Arena evaluation: the doubled HP and increased armor make Knight’s Vow a strong Tank\/Support item in Arena’s duo format \u2014 protecting one partner continuously while gaining significant defensive stats. The SACRIFICE redirection remains identical, and the missing HP regen is partially compensated by the higher HP pool.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83c\udfaf When to Build Knight’s Vow<\/strong><\/h2>\n\n\n\n

Knight’s Vow is most effective when a single allied champion is the primary win condition and needs continuous passive protection throughout the entire game<\/strong> \u2014 not just for one 2.5-second window. The 12% redirection is always-on as long as SACRIFICE conditions are met, making it the most consistent carry protection available in the item shop without requiring any in-game reactions.<\/p>\n\n\n\n
