Measured from matches at all ranks from October 30 to November 1, 2026, starting on the day patch 6833 was released (October 30, 2026), by deadlock-api.com. These are match results, not numbers from the game files, and the most bought items, not a recommended build. Each table counts the items bought in one part of a match, by the game time of the purchase: laning before 10:00, mid game 10:00 to 19:59 and late game at 20:00 or later. "Bought by" is the share of all Rat King matches in which the Rat King player bought the item in that phase, counting matches that ended before it began. The win rate is how often those players won, which describes the players who bought it, not what the item itself adds. The average buy time is the average game time of those purchases, also measured by deadlock-api.com. A copy the Broker corrupted is not counted. An item shows only with at least 500 matches.

Rat King lore
The cryptid ruler of the New York Warrens, The Rat King towers over his subjects in size, strength, and ambition. No longer content with hiding underground, the king has revealed his bold vision for a future where he and his subjects can walk the surface without fear of the pest control vans that roam the streets of New York (or as the rats call them: human death squads)
Step 1: Take control of Long Island
Step 2: Declare Long Island as the new sovereign nation of Ratannia
Step 3: Execute every human that refuses to leave this new rat utopia
But air tight as this plan is, the king of rats didn't want to take chances: and so he's decided to summon the patron to help hedge his bets.

Computed with the matchup lab's formula, body shots with every pellet hitting, level 1, no items: damage per bullet = bullet damage x (1 - defender bullet resist / 100); bullets to kill = ceil(defender max health / damage per bullet); body shots = ceil(bullets to kill / bullets per shot). Each number's tooltip holds its inputs.
Not modelled:
- Headshots: the gun files give a 1.65 bonus, a game setting gives 1.25, and only the game shows which applies.
- Damage falloff over range, and the game-unit to meter conversion.
- Resist shred and negative resist.
- Reload, burst-fire and spin-up timing, so time to kill is shown only when the kill fits in one clip of a gun that neither bursts nor spins up.
- Item procs and actives, spirit damage amplifiers, and ability upgrades (every ability is at its base tier).
- Health regen, barriers and healing during the fight.
