Stats

Values as the League of Legends Wiki's item data lists them, for every mode; the data doesn't state their units.

Effects

• Steadfast (unique): Taking magic damage from champions generates a stack of Steadfast for 7 seconds, stacking up to 8 times with the duration refreshing on subsequent magic damage from them and whenever dealing damage to them. Becoming immobilize by an enemy champion generates 2 stacks and also refreshes the duration. Once per cast instance, each incoming basic attack, ability, or item effect can only generate 1 stack of Steadfast from their damage every 1 second. At maximum stacks, gain 70 bonus magic resistance and 6% bonus movement speed.³
