With a strength gain of 4.3, Primal Beast has the highest strength gain in the game!
A patch ago, it was Centaur with a strength gain of 4.6.
But that was nerfed to 4.0 in patch 7.31, which gives Primal Beast the top spot.
His total attribute gain per level though, falls towards the lower end of the spectrum at 6.7.
The high strength gain and starting armor make him a force to reckon with in the laning stage.
The skill does physical damage and also stuns all those hit by it for 1.6 seconds.
One of the best potential uses of Onslaught is possibly in the Roshan pit.
2) Trample
Trample is an interesting skill.
In a sense, it is attack damage that cannot be reduced by armor.
Trample is not only good for following up after Onslaught, but also a useful skill for farming stacks.
Turning it on and standing in one place in a neutral camp can only cause hurt to the beast.
3) Uproar
Uproar is a great skill to combo with Trample.
Uproar increases Primal Beasts damage, both, passively and actively.
A BKB wouldnt be bad either, but does anyone buy those these days?!
Depends on which team you are on!
On the whole, it is an underwhelming Aghanims Shard upgrade.
The hero is still quite new though, so that is bound to change.
Other than that, there isnt anything to write home about.
Radiance could be a useful item for Primal Beast, especially when going for a right click build.
There are bound to be more buffs on the way for the rampaging monster.
For now, the game calls for experimentation with the newest hero.
