This week vs last week
Basically unchanged — win rate wobbled down about 0.3 points (58.7% → 58.4%), but that's inside the normal week-to-week randomness, not a real move.
p = 7.8e-4 — the odds a swing this big is just luck — too high to trust as a real change across all the heroes we test each week.
Win rate by when it was bought
- 10–20 min65.9% (65.3–66.5, 24,540)
- After 20 min58.2% (58.1–58.3, 795,579)
Buying it later goes with a lower win rate (7.7pp) — a real gap, but remember late buys usually mean you were already ahead.
Read this before trusting the number
An item's win rate is correlational. Expensive late-game items post high win rates largely because you only complete them when your team is already ahead — not because the item is what won the game. Use it to see what the strong builds tend to include, not as a causal "buy this to win" ranking.
Win rate is the share of matches won when this item was bought, over a rolling 7-day window; the trend compares it to the 7 days before with a Bonferroni-corrected two-proportion z-test so a normal weekly wobble isn't reported as a shift. Data from deadlock-api.com, refreshed hourly.
