Hello, I'm Dogeuwdogeuw and hopefully I will teach you how to play graves. I have reached Diamond, Master and Grandmaster playing Graves in the span of one yea. I peaked Rank 2 on graves with a 78% win rate out of 110 games. I belive you can learn the role (as in Jungle) pretty easily if you play Graves. So, let's get started.

Pros: - He can clear jungle really fast.
- He can contest objectives really easy.
- 1v9 potential.
- Really fun to play and master.
- His W is giga broken.
- Good for early/mid/late game.
- Can be blind picked.
- Really versatile.

Cons: - Hard to master.
- No CC.
- His auto attacks can feel clucky at first.
- Short range for a ranged champion.
- Needs to be played like a melle assasin.
- Kinda usseles if he falls behind.
- Can't fight in minion waves.

Graves excelles in full AD team comps because of his true grit passive from E.
You should pick graves if they have a lot of melle/short ranged champions.
Avoid from picking Graves if they have a lot of ranged champions.
Also, champions with a lot of MS or big gapclosers can dodge your basic attacks.

Path 1) Red-Raptors-Wolves-Blue-Gromp-Scuddle (most standard path, good if u have prio mid/top)
Path 2) Red-Blue-Gromp-Wolvez-Raptros-Scuddle (good if you fear of getting invaded)
Path 3) Red-Invade (good if they have weak early game champions)
Path 4) 6 camps into crab( don't really recommend)
Path 5) Two camps into invade (usually blue-gromp-invade)

Graves doesn't have any hard CC like Sejuani or Rammus so you need to be carefull when ganking.
Try to close the gap between the enemy and the tower with your W.
Always stay ahead of the enemy in case he flashes.
Don't fight in minion waves because you will lose.
Don't force ganks. If enemy laners are pushed in just go and invade.

Thank you for reading my guide and I hope I managed to share so tips/tricks about Graves and about Jungle in general.
