StageFavouredWhy
Level 1GnarGnar-favoured: at level 1 his Boomerang and superior auto range let him poke while you cannot yet close distance.
Level 2Even / skillSkill: level 2 is a coinflip — he still out-ranges you but you're one level from W, so trades depend on his rage timing.
Level 3IllaoiIllaoi-favoured: with W Harsh Lesson you can dash onto mini-Gnar and punish his lack of escape.
Levels 4-5IllaoiIllaoi-favoured: levels 4-5 your tentacle count grows and W cooldown drops, so every gap-close chunks him.
Level 6IllaoiIllaoi-favoured: R Leap of Faith punishes any Mega Gnar all-in with an instant tentacle ring.
First itemIllaoiIllaoi-favoured: first item turns your tentacle field into sustained DPS that Mega Gnar can't brawl through.
Two+ itemsIllaoiIllaoi-favoured: at 2+ items Gnar's fragile frame folds in any fight fought inside your tentacles.

How to beat Gnar as Illaoi: the early game
