Bloodthirster

Stats

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

Effects

• Ichorshield (unique): Convert the healing received from life steal in excess of maximum health into a shield for up to 165 + (315-165)/10*(x-1), which lasts until destroyed.³

Arena changes

• Attack damage changed to 70.
• Life steal changed to 18%.⁴

• Bloodthirster is usually a better item against tanks for ranged champions than Blade of the Ruined King; its added damage and life steal amplify critical strikes and provide enough health to face-tank them unless they are permanently crowd-controlled.⁵
• Bloodthirster is recommended over Hextech Gunblade for more attack damage and sustain.⁶
• Bloodthirster is common for standard ADCs as a way to avoid being poked out.⁷
