Slark vs Undying

How this matchup plays

Fighting a Slark is often a matter of surviving his initial burst, but Undying completely changes that dynamic. A well-placed Tombstone makes it incredibly difficult for Slark to disengage or use Shadow Dance to regenerate, since the zombies provide constant vision and chip damage. On top of that, repeated stacks of Decay make Slark much easier to kill than he looks by draining his strength. Slark isn't helpless, though. His Dark Pact provides a crucial dispel, letting him purge the slow from the zombies and the Decay debuff, creating a small window to Pounce to safety or re-engage on a better target.

This back-and-forth defines the matchup at all stages. Laning against Undying is punishing for Slark, who prefers to trade health. In mid-game teamfights, everything hinges on that Tombstone. If Slark can't quickly destroy it or find a pick-off on the edge of the fight, he'll find himself swarmed and unable to slip away. The game often becomes about Slark trying to split the map and avoid Undying's five-man push, while Undying's team tries to force fights where his area denial shines brightest.
