The Collector

Stats

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

Effects

• Death (unique): If you deal post-mitigation damage that would leave a champion below 5% of their maximum health, execute them.
• Taxes (unique): Killing a champion grants you an additional 25.³

Arena changes

• Attack damage changed to 45.
• Lethality changed to 12.
• Taxes bonus gold per kill changed to 125.⁴

• Against Nesting Doll, The Collector is an honorable mention; farm the opponents.⁵
• For an AD assassin build, one baseline is a lethality prismatic, The Collector, Lord Dominik's Regards or an anti-heal item, and Infinity Edge.⁶
• With Upgrade Collector, damage-over-time augments and attack-speed steroids can make The Collector stronger.⁷
• Keep The Collector for its execute and critical-strike synergy. Mystic Punch with repeated blind casts, Ethereal Weapon, Dragonheart with Ocean, and penetration items, Rabadon's Deathcap, or Terminus also fit the build.⁸

After Collector's upgrade is finished, it stays upgraded if its augment is replaced.⁹

Earlier formats

• Since patch 14.17, The Collector has 12 lethality, down from 18.¹⁰ 8x2 duos

Damage numbers occurring in the same tick were combined into one number, so The Collector did not always display 999.¹¹ 8x2 duos

• The Collector paired with Hubris in a Pyke build focused on lethality and ultimate executions.¹² 8x2 duos
• Buying The Collector and refunding it each round was a way to kill the dummy for 150 gold per round.¹³ 8x2 duos
• The Collector was a good buy in a Nesting Doll game because it could provide up to six kills and 250 plus 750 gold per round.¹⁴ 8x2 duos

Champions with executes could focus on lowering enemies' health enough to use the execute, rather than increasing the execute's damage with The Collector or Shadowflame.¹⁵ 8x2 duos
