Hello, my name is DeathTheGreat on EU West server and I wanted to share what I consider one of the strongest junglers in the game, If people leave feedback I will extend on this guide to make it even better.

My build mostly focuses on Volibear's primary damage tool Frenzy
Allowing for quick jungle clears and more reliable damage to finish of your victim's when ganking.

With my build I'm sure some of you will have more luck winning games with my own experience playing this Champion.

This image shows the first camps you should be taking in order for you to pull off some succesful early ganks, as soon as you see gromp spawn Smite it for the most possible damage for faster clears.

Once you've done that initial order you can look to see for potential easy ganks at mid or top, if the enemies aren't over-extended you can just finish off the rest of the camps and create river vision at the scuttle crabs

1.) When using Rolling Thunder to gank just before you reach an enemy use Majectic Roar to help close the gap easier.
2.) Always Always try to save Frenzy when the enemy is like 30% hp to secure a kill instead of wasting it when they are healthy due to the bonus damage it gains and it's high cooldown.
3.) When taking either Drake / Baron take advantage of Frenzy's execute damage to it's full potential; instead of finishing off the monster with Smite, use Smite first then instantly use Frenzy to burst it down more efficiently.
4.) When jungling use Majestic Roar more efficiently by fearing large monsters near the end of their attack animation to keep you healthier in the jungle.
5.) Later into the game don't be afraid to use the Flash + Rolling Thunder combo to pick someone off out of position.
6.) Try to save Thunder Claws for teamfights due to it's long cooldown as it's best used for crowd control damage.

PROS:
Very hard to kill early and late game due to his passive Chosen Of The Storm
Very high burst damage to secure Drake / Baron or kill squishy people in teamfights
Very good at roaming to secure kills for your team

CONS:
Very prone to getting kited from CC especially if you go boots of mobility so positioning is key
Doesn't handle being bursted down due to his tankiness depending on his hp regen passive (counter-act bursty team comps with Steraks Gage to help you survive enough for your passive to kick in)
