Notes

• If the attack is a normal critical strike it will deal 160% of the enemy's AD, instead of 200%.
  • If the enemy also has Infinity Edge, it will deal 180% of the enemy's AD, instead of 225%.
• Warden's Mail, Thornmail, Frozen Heart, and Randuin's Omen are the only items that can reduce  attack speed.
  • The attack speed slow on Warden's Mail, Thornmail and Randuin's Omen do not stack with each other, however they do stack multiplicatively with Frozen Heart for a combined 27.75% attack speed slow.
• Randuin's Omen's  critical strike damage reduction against abilities only applies for those that act like a basic attack (i.e Lightslinger) and those that grant modified damage (i.e Ruthless Predator). It doesn't apply for those that only deal bonus damage (i.e Mounting Dread, but note that it still applies for the base damage).

Strategy

• Randuin's Omen is a strong counter against basic attackers that stack well on  Critical strike chance, like Graves, Yasuo and Tryndamere.
