Stomps over everything and smashes enemies into messy bits

As the only member of his species to arrive on this world, locals can only speculate on the Beast's size relative to his kin. Such observation would prove easier of course if the subject didn't eat everything it sees and destroy most of what it doesn't.
Uproar
PASSIVE: No
The Beast's temper causes every instance of 50 hero damage or more to grant a stack of Uproar. When activated, Primal Beast releases a roar that slows surrounding enemies and grants the Beast additional attack damage and armor for 7 seconds based on his current stacks of Uproar.
Primal Beast cannot gain Uproar stacks from self damage.
Break disables the gaining of new stacks.

Strategy
Your base damage and Uproar passive and active effects allow you to win the last hit battle against opponents in the laning stage.
Use Onslaught when opponents are somewhat stationary, for example when they are going for a last hit.
You want to use Uproar when Trampling over the opponents heroes for maximum damage.
Take your time and farm 
Blink Dagger so you can instantly Pulverize an opponent.
Try to Pulverize an enemy hero standing in the middle of the enemy lineup so you can stun the rest as well.
When not much is happening, push out side lanes with your AoE damage abilities.
Pick up 
Aghanim's Shard later in the game as it provides another disable from long range.
Use Trample right as you exit the Onslaught channel to use the charging movement for Trample damage.
Against a tough lane, you can Trample and kill the first wave behind the enemy tier 2 tower.
Counter Strategy
Avoid staying still against Primal Beast. Move around and be ready to dodge the Onslaught.
Stun, fear, hex and silence effects can stop Pulverize.
Spell immunity counters all of the Primal Beast's abilities other than Uproar.
You can always interrupt Pulverize before completion if you are in range with a stun or silence.
