Standard clear:

Most of the time you start on Red and then go raptors ---> wolfs ---> blue ---> gromp and gank or wait for crab and try to catch enemy jungler off guard.

You can also start red and do full clear.

Fast gank:

If you play with friends you can also do fast 3 camps and gank their lane if you get good set up for gank.

Always start gank with your Q and E behind enemy (to slow them if they want to run + shield for you), if you have ghost and lane is pushed towards your tower it's almost always 100% kill for you or your laner.

Jax

When you want to gank jax make sure that your laner bate his E before gank, otherwise he can block you Q with his E and jump away with Q or cc your with his E and then you just lost your time.

Vayne

Very helpful, if she doesn't has her E, otherwise she can push you back and q towards her tower.

Veigar

Similar to jax if he has his E it's impossible for you to gank him, so your laner must bait his E before gank.

Akshan

Very bad ganks when his E is up.

Camille

Same as Akshan.

With this build and runes volibear is very strong in the mid/late game if you feed very fast in early game but if you fall behind it's very hard for you to get back into game.
