Tips
Use your passive to leap from bushes for surprise engages and to stack Ferocity quickly.
Build lethality items like Duskblade to maximize burst damage on squishy targets.
Save your Empowered Bola Strike to root key enemies before they escape or use abilities.
Activate your ultimate to scout and pick off isolated carries in the narrow ARAM map.
