The style of play of this hero is really simple and characteristic. It 'a murderess quick and fast that exploits the potential ranged and melee ALWAYS.
You can get out of a bush, kill an enemy and disappear into the shadows.
In this guide, I preferred the wolf form because besides being the most effective is the most sneaky.
You can have fun and try it if you like! And when you come to leave positive feedback for me that you tried good.

Good hunting!

Other choice:
Tier 1: Scented Tincture - If you play against invisible.
Tier 4: Go for the Throat - If your enemy are squishy.
Tier 5: Running Wild - Valid spell, for close the distance
Tier 6: Extecutioner - If in your team you have stun/slow.// Alpha Killer if you play against two or more tanky heroes.

Variant for the human form, not even comment, I did it for those who are bored to form the beast. And 'as good but less spectacular!
