Tip overview

His insta heal is big, but only when ally is in his circle. Firstly you and "your allies" should pay attention to "his allies" and them occupy with something. Then when Grover is left alone it's your chance to challenge him on solo fight.

If a Grover is by himself, this can give any champion with decent mobility a chance to close the distance between them and Grover. The closer you get, the more damage you do and the less damage Grover does. Don’t forget about the vine though!

Grover is NOT CC immune during his ultimate, however if he is stunned/chickened it will not interrupt his healing AOE.

Don't embrace a fight when he is using his ultimate. It heals a lot of life points of all nearby enemies

Grovers axes do the more damage the farther they are flying. Don't get sniped!
