Why this duo works
Mundo's durability gives Briar a frontline to play behind, while Infected Bonesaw(Q) slows a target so she can close and commit. Their sustained fighting lets Mundo absorb attention as Briar dives onto a priority target.
Playing the duo
Use Mundo's Infected Bonesaw(Q) slow as the go-signal for Briar to commit with Blood Frenzy(W) or Certain Death(R), then stay on the same target so the slow and Briar's control overlap.
Infected Bonesaw(Q) slows its target, giving Briar a clear opening to follow with Head Rush(Q) or Blood Frenzy(W) instead of starting the chase from range.
Mundo's Maximum Dosage(R) and Briar's Crimson Curse(P) sustain them through long fights, so Mundo can hold the frontline while Briar takes the deeper dive.
How to play as Dr. Mundo
Follow Briar's first dive instead of starting a separate chase; your health and Maximum Dosage(R) help absorb the peel, while your Q slow can catch anyone who escapes her first rotation.
