Strategy

  • Randuin's Omen item.png Randuin's Omen is a strong counter to Blade of the Ruined King item.png 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 (JaxSquare.png Jax, KogMawSquare.png Kog'Maw, TeemoSquare.png Teemo, TristanaSquare.png Tristana, UdyrSquare.png Udyr, and VayneSquare.png Vayne).
  • Warden's Mail item.png Warden's Mail, Frozen Heart item.png Frozen Heart, and Randuin's Omen item.png Randuin's Omen are the only items that can reduce attack speed. The attack speed slow on Warden's Mail item.png Warden's Mail and Randuin's Omen item.png Randuin's Omen do not stack with each other, however they do stack multiplicatively with Frozen Heart item.png Frozen Heart for a combined 27.75% attack speed slow.
  • Randuin's Omen item.png Randuin's Omen is commonly purchased by tanky melee DPS champions, especially the manaless champions like DrMundoSquare.png Dr. Mundo, GarenSquare.png Garen, LeeSinSquare.png Lee Sin, and RenektonSquare.png Renekton that don't benefit from Frozen Heart item.png Frozen Heart because of the mana it gives.

Notes

  • Randuin's Omen item.png Randuin's Omen is named after former Riot employee Robin 'Randuin' Liao.
  • By itself, Randuin's Omen active effect would increase to 2.35 seconds.
  • Randuin's Omen item.png 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.
  • Randuin's Omen item.png Randuin's Omen is the only item in which the crowd-control duration from the active effect scales with the wearer's stats.
