Jarvan makes excellent use of Electrocute in all scenarios as his **[W]** count as a hit ability, so a basic combo at level 3 procs it.

Both Jarvan's **[E] + [Q]** combo and **[R]** proc the bonus lethality for more kill potential.

Placing pinks and clearing wards is key to any successful Jungler, so why not earn some AD in the process?

Getting around the map to join fights and match roams is important as any Jungler.

The bonus healing from Triumph allows you to dive the backline for the quick assassination kill and survive with enough health to get out.

More Attack Speed means a faster and healthier jungle clear resulting in earlier and more often ganks.
