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

Recipe

• Giant's Belt (1000g)
• Warden's Mail (1100g)
  • Cloth Armor (300g)
  • Cloth Armor (300g)
  • 500g
• 1000g

Strategy

• It is worth mentioning that 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, and Lee Sin that don't benefit from Frozen Heart so much.
• The actual formula for Randuin's Omen's active duration is 2 + ([armor + magic resistance]/100) seconds, which means that every point of armor or magic resistance increases the duration and not just steps of 100.
• Master Yi's Meditate will apply an additional 6 seconds of slow if the active is used while during the channel, but will immediately break the channel

Trivia

• Prior to V1.0.0.152, Randuin's Omen, Locket of the Iron Solari, Morello's Evil Tome, Youmuu's Ghostblade, Shurelya's Reverie, and Deathfire Grasp were part of a sextet of "sister items" that shared the similar features such as an active ability and a gold-generating item in their recipe.
• 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.
