Playing against Nocturne

How to counter and exploit weaknesses

1

When the screen goes dark (R), group up immediately: Nocturne is looking for the isolated carry.

2

His W only blocks one ability: bait it with a small spell before throwing your main CC.

3

Nocturne is an assassin who scales with attack speed — hard CC stops him dead while he's auto-attacking.

4

Deep ward in your jungle: his R range is limited, and vision helps you spot him before he arrives.
