Playing against Gnar

How to counter and exploit weaknesses

1

Gnar is vulnerable right after losing Mega form: he's small, has no CC, and his abilities are on cooldown.

2

Watch his rage bar: when it's almost full, back away from walls — his R stuns against walls.

3

Mini Gnar is squishy and can be all-inned — force fights when he's in Mini form with low rage.

4

Don't group up near walls when Mega Gnar is in the fight — he's looking for a multi-target R.
