Playing against Dr. Mundo
How to counter and exploit weaknesses
Grievous Wounds is MANDATORY against Mundo — his R regenerates up to 50% of his max HP.
His Q is his only gap-closing tool: dodge it and he can't catch you.
% max HP damage (Vayne W, Kog'Maw, Liandry's) counters him since he stacks HP but few resistances early.
Ignore Mundo in teamfights if possible — focus the carries and kite him, he deals little damage compared to his tankiness.
