The Viscous build

Each tier lists the items Viscous players win with most often, out of 152,558 Viscous games. Win % is how often Viscous wins when the item is bought; the green or red number is how far that is above or below the rest of the same tier. Popularity is the share of Viscous games the item was bought in; Bought at is the average time. Only items bought in at least 1,500 games and by at least 5% of Viscous players count, so a lucky streak can’t make the list.

Fewer Viscous players buy these, usually against particular enemies, but those who do win clearly more than the rest of the same tier. Each still has at least 1,500 games behind it.

Popular, but behind the rest of their tier

Not wrong to buy, and sometimes the right answer to a specific enemy. On average, Viscous players who buy these win less than those who buy something else at that point.

How this build is chosen

Source: deadlock-api.com item results for Viscous, City Never Sleeps matches since 2026-09-30, refreshed daily. Items are compared with the rest of their own tier, because late items always show higher raw win rates (only players who are ahead can afford them). Ranking uses the low end of each item’s 95% confidence range, so more games beat a lucky few. It shows what winning Viscous players buy; it can’t prove the item caused the win. For what to change against a specific enemy team, use the matchup tool.
