A bow and sixty-four arrows, but heavily reduced damage — and Slowness I for 3 seconds on every hit.
The Yumi is the anti-Archer: where the Archer finishes the wounded, the Yumi prepares the living. A slowed target cannot break away, cannot dodge, and becomes your team's problem rather than yours.
It is a kit that never climbs the kill leaderboard. It is also the one that decides the most fights.
