Primal Beast

Your base damage and Uproar passive and active effects allow you to win the last hit battle against the opponents.

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 opponents lineup so you can stun the rest as well.

When not much is happening, push out sidelanes with your AoE abilities.

Pick up Aghanim's Shard around minute 15 as it provides another disable among other things.

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.

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 Beasts abilities but Uproar.

You can always interrupt Pulverize before completion if you are in range with a stun or silence.
