Willo's seedlings are lethal against Maeve. The only way to escape from that is using the F and wait until they are completely blown up. If your F is on cooldown, use Pounce, jump and heal with Nine Lives.

If you are playing Willo and a Maeve is focusing you, try to look down and use your Q in your place, so that when Maeve tries to Combo you, your Seedlings will explode in your area and she will receive a lot of damage or die instantly
