Fiddlesticks

Your R (Crowstorm) deals MASSIVE AoE damage — channel from fog of war or behind a wall for the fear effect.

The passive places effigies that mimic a motionless Fiddle — place them in key bushes to deceive enemies and zone off entrances.

W (Drain) heals enormously if you channel on multiple targets — use it on camps or minion groups for sustain.

The perfect combo: R from a bush → enemies are feared → W for AoE drain → E for silence → Q on the key target.

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

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

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

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