Playing against Fiddlesticks

How to counter and exploit weaknesses

1

Ward flanking paths and behind walls: Fiddlesticks' R is devastating from ambush but weak when seen.

2

His W channel can be interrupted by CC — a stun or knockup cancels his sustain immediately.

3

Q fear is targeted but has short range — long-range champions counter him well.

4

Spread out in teamfights: his R + W deal massive area damage if you're grouped.
