Why Garen is favored
Decisive Strike(Q) clears Infected Bonesaw(Q)'s slow, letting Garen choose when to disengage and reset his health. Garen players recommend pressuring Mundo early and using Demacian Justice(R) before Maximum Dosage(R) restores his health, which gives Garen a modest LOW ELO edge while Mundo's healing makes late kills harder.
How to play as Garen
Dodge Infected Bonesaw(Q); if it slows you, use Decisive Strike(Q) to clear it before you commit or retreat. Pressure early, and use Demacian Justice(R) while Mundo is low before he activates Maximum Dosage(R); disengage if his healing has already reset the fight.
Infected Bonesaw(Q) slows Garen, but Decisive Strike(Q) removes slows, giving him a way to break the slow when he chooses to engage or leave.
Perseverance(P) restores health only after Garen avoids recent damage, so Infected Bonesaw(Q) can keep it inactive when Mundo lands the poke.
Maximum Dosage(R) heals Mundo on activation and continues regenerating health, while Demacian Justice(R) is Garen's low-health execute; Mundo's recovery changes Garen's kill window.
How to play as Dr. Mundo
Use Infected Bonesaw(Q) when Garen backs away to keep Perseverance(P) from restoring his health. Activate Maximum Dosage(R) before Garen brings you into Demacian Justice(R)'s lethal range instead of waiting until you are nearly dead.
