Singed

Strengths

Poison Trail is very effective at farming and harassing, allowing Singed to dominate the flow of whatever lane he's in.
Use Insanity Potion to trick your opponents into chasing you through your Poison Trail.
Flinging enemies into your tower can deal heavy amounts of damage to them.

Passive · Noxious Slipstream — Singed drafts off nearby champions, gaining a burst of Move Speed when passing them.
Q · Poison Trail — Leaves a trail of poison behind Singed, dealing damage to enemies caught in the path.
W · Mega Adhesive — Throws a vial of mega adhesive on the ground, slowing and grounding enemies who walk on it.
E · Fling — Damages target enemy unit and flings them into the air behind Singed. If the target Singed flings lands in his Mega Adhesive, they are also rooted.
Ultimate · Insanity Potion — Singed drinks a potent brew of chemicals, granting him increased combat stats, and making his Poison Trail apply Grievous Wounds.

A suggested 5-lane lineup built around Singed, based on hero partnerships and role synergy — not win rate.
