What is Randuin’s Omen? \ud83d\udee1\ufe0f<\/strong><\/h2>\n\n\n\n

Randuin’s Omen is a legendary Tank item<\/strong> in League of Legends, categorized under Tank, Health & Regeneration, and Armor. It is the primary anti-critical-strike tank item<\/strong> in the game \u2014 specifically designed to counter marksmen and crit-building champions through two mechanisms: the HUMILITY active that forces grouped enemies into a 70% slow, and the RESILIENCE passive that reduces all incoming critical strike damage by 30%.<\/p>\n\n\n\n

The RESILIENCE passive is Randuin’s Omen’s defining identity. Against a standard crit ADC dealing 200% AD on crits<\/strong>, RESILIENCE reduces that to 140% AD<\/strong> per critical strike \u2014 a 30% multiplicative reduction. Over a teamfight where an ADC fires multiple crits into the tank, this reduction accumulates into meaningful effective HP. No other single item in the game provides direct critical strike damage mitigation at this level.<\/p>\n\n\n\n

At 2,700 Gold<\/strong>, it is competitively priced for a tank item. Sell price: 1,890 Gold<\/strong>. ID: 3143. Available on SR 5v5, ARAM, Nexus Blitz, and Arena.<\/p>\n\n\n\n

\ud83d\udca1 Warden’s Mail \u2014 Strong Armor Mid-Item vs Basic Attack Dealers<\/strong>Warden’s Mail (1,000g) provides pure armor as a first-back or mid-item purchase.It also has its own passive (Cold Steel on SR): attacks against you reduce attacker’s attack speed.Against heavy basic attack compositions (Fiora, Tryndamere, marksmen), Warden’s Mail early provides meaningful attack speed slowdown before Randuin’s Omen completes.Giant’s Belt (900g) provides the HP foundation \u2014 buy whichever is needed first based on the incoming damage type.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\u26a1 Active Mechanic: HUMILITY<\/strong><\/h2>\n\n\n\n

HUMILITY unleashes a shockwave in a 500 range area around the caster<\/strong>, slowing all nearby enemies by 70% for 2 seconds<\/strong>. Cooldown: 90 seconds<\/strong>.<\/p>\n\n\n\n

\u26a0\ufe0f HUMILITY Spell Shield Bug \u2014 Important Interaction<\/strong>HUMILITY breaks spell shields (Banshee’s Veil, Edge of Night, Sivir E) on cast.However, it STILL applies the 70% slow to the spell-shielded target regardless \u2014 this is a documented bug.Practically: Randuin’s Omen HUMILITY will consume a Banshee’s Veil AND still slow the target.This makes HUMILITY functionally unblockable for its slow effect \u2014 spell shields cannot prevent the slow.The bug has persisted through multiple patches \u2014 treat HUMILITY as always landing the slow regardless of spell shield status.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
\ud83d\udca1 HUMILITY \u2014 70% Slow Is the Strongest Slow in the Game from a Single Source<\/strong>70% slow reduces a 340 base movement speed champion to 102 effective movement speed for 2 seconds.No standard mobility ability can escape a 70% slow in 2 seconds \u2014 even 550 MS champions are slowed to 165 MS.In grouped teamfights within 500 range, all 5 enemies simultaneously hit with HUMILITY creates a 2-second window where the entire enemy team is effectively immobilized.Combining HUMILITY with zone control abilities (Orianna R, Kennen R, Amumu R) during the 2-second slow window is one of the most decisive engage patterns in the game.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83d\udee1\ufe0f Passive Mechanic: RESILIENCE<\/strong><\/h2>\n\n\n\n

RESILIENCE reduces incoming damage from critical strikes by 30%<\/strong>. This reduction is applied multiplicatively<\/strong>, not additively.<\/p>\n\n\n\n

RESILIENCE \u2014 How the 30% Reduction Actually Works<\/strong><\/h3>\n\n\n\n

Against a standard crit at 200% AD: RESILIENCE applies a 0.70 multiplier<\/strong> (1 – 0.30 = 0.70), reducing the hit to 140% of the enemy’s AD<\/strong> instead of 200%. This is a direct 60 AD reduction in damage per crit at the 200% crit threshold.<\/p>\n\n\n\n
