WhyPress the Attack

With a Tiger Stance focused build, Press the Attack synergizes incredibly well with your ability to quickly proc the exposure damage and stack the bleeds for rapidly increasing damage.

WhyTriumph

Triumph allows you to dive into the enemy and slice them up in teamfights and keep on going thanks to the massive heal after each kill.

WhyLegend: Alacrity

More Attack Speed means a faster/healthier jungle clear, more map control, and much faster kills/stack of Press the Attack.

If you're playing into a lot of hard CC and think you'll have a hard time getting to priority targets, Tenacity is a solid alternative.

WhyCoup De Grace

Coup De Grace is the go-to rune for slicing up squishy targets as quickly as possible. The execution damage allows your double-stacked bleeds to hit like a truck.

WhyCelerity

Celerity empowers your ability to traverse the map much more quickly than otherwise possible, allowing you to power-farm and hit item/level power-spikes way sooner than the enemy is expecting.

WhyWaterwalking

Waterwalking furthers your ability to control the jungle with map presence. The extra AD also allows you to sneak some early dragons/Rift Herald for more objective control.
