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 shoots individual missiles to affected targets to indicate the buff being applied to them.
  • These are not considered projectiles.
• Critical Resilience's  critical strike damage reduction is applied multiplicatively.
• Critical Resilience's  critical strike damage reduction also affects abilities that critically strike, but only those that are treated like a basic attack or deal modified damage. The reduction does not apply to those that deal bonus damage.
• With Randuin's Omen itself, Rock Solid grants 6.4 flat damage reduction.

Strategy

• Randuin's Omen is the most effective against champions that deal physical damage with their attacks, especially when they critically strike.
• Randuin's Omen's active is best used in situations to chase down vulnerable targets or run away from approaching threats.
