Notes

• Humility is not blocked by spell shield.
• Humility is an auto-targeted effect.
• Humility's cast breaks stealth.
• Humility has no cast time.
• Humility's attack damage reduction can affect any unit, including epic monsters.
• Humility's  critical strike damage reduction is applied multiplicatively.
• Humility's  critical strike damage reduction 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).
• Humility shoots individual missiles to affected targets to signify who is being given the debuff.
  • These are not considered projectiles.
• On its own, Randuin's Omen grants 5.875 flat damage reduction.

Strategy

• Randuin's Omen is a strong counter against attackers that usually critically strike on their basic attacks, like Yone, Yasuo and Tryndamere.
