Randuin's Omen is a legendary item in League of Legends.

Recipe

• Giant's Belt (1000g)
• Warden's Mail (1000g)
  • Cloth Armor (300g)
  • Cloth Armor (300g)
  • 400g
• 1000g

Cost Analysis

Gold Value

• 500 health = 1319g
• 70 armor = 1400g
  • Total Gold Value = 2719g

Gold efficiency

• The passive and active must have at least a combined valued of 381g for Randuin's Omen to be gold efficient.

Strategy

• Randuin's Omen is a strong counter to Blade of the Ruined King, as it provides armor, health, an attack speed slow and a movement speed slow; and the two actives mostly mitigate each other.
  • It is also useful against champions that are highly reliant on auto-attacking as means of damage output ( Tristana, Kog'Maw, Vayne, Teemo, and Jax).
• Warden's Mail, Frozen Heart, and Randuin's Omen are the only items that can reduce attack speed.
• Randuin's Omen is commonly purchased by tanky melee DPS champions, especially the manaless champions like Dr. Mundo, Garen, Lee Sin, and  Riven that don't benefit from Frozen Heart because of the mana it gives.
• Using the active on Randuin's Omen while your champion is channeling an ability will end the channel prematurely.

Notes

• Randuin's Omen is named after former Riot employee Robin 'Randuin' Liao.
• Randuin's Omen's active effect's debuff is named Black Omen, possibly a reference to the floating palace bearing the same name from the game Chrono Trigger.
