Stomps over everything and smashes enemies into messy bits.
An ancient beast awakened from a long slumber, he uses a wide array of savagely cunning abilities which can impede the enemy groups. Rushing savagely through enemies and allies alike, Primal Beast Tramples into battle as one born to raise a ruckus. An unavoidable threat amidst any fray, the Uproared Beast can punish attackers. It relishes grabbing prey and Pulverizing them against the ground until nothing but mush remains. A fearsome beast, the Primal Beast shows no mercy to his helpless prey as the epitome of a true apex predator.

Primal Beast minimap icon.pngPrimal Beast
Though the deterioration of the Mistwood and its evolution from idyllic expanse to death-filled tanglewild was a slow, wizard-fueled process, most scholars agree the true beginning of the end was marked by the interdimensional arrival of the Primal Beast. A creature hatched into an existence devoid of all feeling but hunger and pain, aeons of carnage shaped the Primal Beast into the apex predator on a planet filled with violent terrors. Desperately banished by would-be masters with failed hopes to control him, the Beast was cast into a new world — one where he could ascend from mere hungry predator into an invasive killing machine with nothing able to stand in his way.

For thousands of years, the Mistwood served as massive stomping ground for the Beast's destructive play — and even the feared durana beasts made for tasty snacks. Indeed, there could be no rivals for the Beast's territory, only minor annoyances. Until one such tiny annoyance employed vile trickery to trap the unstoppable Beast in the Gleipnir.

There he might have remained subdued for eternity, were it not for the unpredictable powers of the Continuum Device. Now, freed from both Gleipnir and Vault, far afield from the Mistwood, and much closer to inhabited lands, the Beast sets his snout towards new slaughters and the delights of savage destruction — and the paltry fires of civilization will do little to keep this ageless monster at bay.

Onslaught icon.png
Primal Beast charges up and then runs in the chosen direction, knocking back enemies and allies alike. Enemy units are damaged and stunned on impact. The longer the charge duration, the farther Primal Beast's momentum will carry him.

Can be cancelled at any time with the Stop command.

The Beast's single-minded focus on chosen prey leaves all other considerations scattered in his ruinous wake.


  • The maximum distance can be further increased by other cast range bonuses.
  • Upon cast, the direction can be changed with a move order (Keyboard White Mouse Right.png Right Click or M).
    • A line indicator is cast in front of Primal Beast while aiming the charge, showing the path it will take once released.
    • The indicator is visible to the player only. Neither allies nor enemies can see it.
  • Goes on cooldown once the charge ends or is cancelled, not upon cast.
  • The charge is not cancelled by taunts. Instead, Primal Beast starts attacking the taunting unit once the charge stops.
    • Onslaught cannot be manually cancelled during taunts.
  • Being silenced during the casting phase will not interrupt the ability. It will instead force you to complete the cast and charge the maximum distance, as it is not possible to cast the ability again to charge prematurely.
  • For better readability, the turn rate before the Onslaught begin is given as degrees per second, instead of radians per 0.03 seconds.
    • 70° per second equal a turn rate of 0.037.
  • Primal Beast can still perform other actions during the charge time. Non-targeted abilities and items are used normally.
    • However, targeted items that require facing can only be cast when targeted within its current facing direction.
    • Targeting outside its facing direction causes it to get locked in position until the stop (S) or hold command are used.
    • The turn rate is reduced to 50° while charging. It effectively reduces the turn rate to 0.87 for that time.
  • Primal Beast is disarmed during Onslaught. Attack orders behave like move orders during disarms, and it sets a new location as well.
  • Once released, Primal Beast begins charging and any unit which comes within 190 radius of Primal Beast during the charge gets damaged.
  • Onslaught first applies the debuff, and then the damage.

Sub-ability of Onslaught.


  • Replaces Onslaught until the sub-ability is used, until the charge starts or until a Stop command (S) is issued.

Trample icon.png
No Target
Primal Beast stomps over everything. For every 140.0 units traveled, all enemies around the Beast receive damage. Deals base damage plus a multiplier of Primal Beast's attack damage. Primal Beast is disarmed for the duration of the ability.

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.


  • Trample does not interrupt Primal Beast's channeling abilities upon cast.
  • Primal Beast is disarmed during Trample. Attack orders behave like move orders during disarms, and it sets a new location as well.
  • Trample releases a single pulse of damage only when Primal Beast collectively moves a distance of 140.
    • This means no damage is dealt if Primal Beast is not moving.
    • Forced movement
    • Teleporting effects (including Blink-based abilities)
    • This means long-distance teleports may only release one pulse, and not multiple pulses based on the entire distance.
    • The distance counter has no time limit. It only resets upon releasing a pulse
  • This means the higher the movement speed, the higher the frequency of damage done.
    • Considering Primal Beast's base movement speed and the max movement speed limit, Trample can deal up to 2.18 ‒ 3.93 instances of damage per second.
  • The amount of damage dealt per instance is directly proportional to Primal Beast's current damage, including any bonuses from items or abilities.

Self / Enemies
The Beast's temper passively provides base bonus damage. Additionally, for every instance of 50 damage or more Primal Beast takes from enemy heroes, he accumulates stacks of Uproar.

When activated, Primal Beast releases a roar that slows surrounding enemies and grants the Beast additional attack damage and armor for 7.0 seconds based on his current stacks of Uproar.

Already draped in a broken patchwork of barding and chains upon appearing in the mistwoods, the Beast tolerates no further attempts at subjugation.


  • The number of current Uproar stacks is shown as 3 different ability icons, starting with no stacks, 1 – 4 stacks and max stack.
  • For how much bonus attack damage and bonus armor Uproar grants (including movement speed reduces) up to 5 stacks on each level, please refer to the chart below.
    • Reduces affected targets' movement speed by 40%.
    • Increases Primal Beast's bonus attack damage by 60/115/170/225 and armor by 5/10/15/20 (Talent 20/25/30/35) at max stack.
  • Applying another stack of Uproar refreshes the duration of previously applied stacks. When the stack buff times out, instead of losing all charges at once, they will decay rapidly over the span of roughly half a second, allowing the ability to be triggered slightly beyond its maximum duration.
  • The ability icon shows the remaining buff duration in red as cooldown upon cast. However, this has only informative purposes.
    • The cooldown is not affected by any cooldown reduction and cooldown resets sources.

Aghanim's Shard Upgrade:
Grants the Rock Throw ability.
Though none are certain whether his utterances have true meaning, most concede the Beast's powerful grip and tendency to smash his enemies into naught but pulp and pieces communicates his intent well enough.


  • With the maximum channel time, it can stun affected enemies within radius up to a total of 3 (Talent 6) times.

Recommended Items[]

Starting items:

  • Two sets of Tango icon.png Tango's are very handy for trading for Uproar stacks early on.
  • Two Gauntlets of Strength icon.png Gauntlets of Strength are very strong, and turn into much needed Bracer icon.png Bracer's later.
  • Two Iron Branch icon.png Iron Branch's are great for building into an eventual Magic Wand icon.png Magic Wand.
  • A Quelling Blade icon.png Quelling Blade might be a great idea if you are struggling to last hit your own creeps.
  • Buying a Healing Salve icon.png Healing Salve for yourself is not unheard of to do later on if you need it.

Early game:

  • Magic Wand icon.png Magic Wand provides some attributes and to restore health and mana. Magic Wand icon.png Magic Wand works well with Uproar, because to maximize the effect of Uproar, he should accept damage first, and Magic Wand icon.png Magic Wand can be used to restore the health lost during this.
  • Buying a Bracer icon.png Bracer or two is very common because at minute 25 it gives an additional 400 health.
  • Boots of Speed icon.png Boots of Speed gives a higher base move speed, increasing the effectiveness of Trample.
  • Phase Boots icon.png Phase Boots can be activated during Trample to increase the damage but also gives much needed survivability to physical damage and enables phased movement for a short period of time.
  • Infused Raindrops icon.png Infused Raindrop is amazing against certain heroes who can do low cooldown magical damage to you from a distance.

Mid game:

  • Black King Bar icon.png Black King Bar is important against heroes who can disrupt Primal Beast from casting his spells for maximum damage. It's also very handy if you find yourself in over your head, as a simple bkb tp might save you due to your high health.
  • Vanguard icon.png Vanguard or Hood of Defiance icon.png Hood of Defiance can be terrifying for your opponent and you will usually want one of these.
    • Note that Vanguard icon.png Vanguard can prevent Primal Beast from gaining stacks of Uproar by reducing the damage below the necessary threshold.
  • Kaya and Sange icon.png Kaya and Sange is a very good option because it can be disassembled into two very good items on Primal Beast, Ethereal Blade icon.png Ethereal Blade and Heaven's Halberd icon.png Heaven's Halberd.

Late game:

  • Heart of Tarrasque icon.png Heart of Tarrasque grants Primal Beast a significant amount of health, damage and regeneration. In addition to this, as with all strength, damage, and movement speed increases, this item will synergise well with Trample.
  • Ethereal Blade icon.png Ethereal Blade can be upgrade from Kaya icon.png Kaya and provides a way to both prevent right clicks and slow enemies while amplifying your spells' damage. It can also be used in a pinch to save allies if need be.

Situational items:

  • Blink Dagger icon.png Blink Dagger combined with bkb, making Primal Beast can initiate using Pulverize without interruptions. Keep in mind you can also initiate with Onslaught.
  • Overwhelming Blink icon.png Overwhelming Blink active, makes Primal Beast can deal more damage to enemies during initiation. Overwhelming Blink icon.png Overwhelming Blink also boost Primal Beast's strength, increasing his durability, attack damage and Trample in the late game.
  • Soul Ring icon.png Soul Ring gives much needed mana, but is not always needed if you have a magic wand and are getting charges.
  • Heaven's Halberd icon.png Heaven's Halberd can prevent heavy hitting carries from damaging you or your team, allowing you to initiate and fight without being burst down. Every single stat helps Primal Beast, but is situation due to the other options being more ideal unless the enemy carry is that concerning.
  • Eternal Shroud icon.png Eternal Shroud improves survivability by increasing magic resistance even further over Hood of Defiance icon.png Hood of Defiance.
    • The spell lifesteal allows Primal Beast to recover health when using Trample and Pulverize, each of which can do significant magic damage to multiple targets at a time. The spell lifesteal talent stacks additively with other sources of spell lifesteal,
    • Additionally, the active ability can be used to regenerate mana during a teamfight, whilst blocking incoming magical damage. This helps supplement Primal Beast's naturally small mana pool.
  • Radiance (Active) icon.png Radiance adds additional damage, which improves farming capability and the effectiveness of Trample. It also increases survivability through its aura and evasion, as Primal Beast tends to be in the front and center of team fights.
    • When combined with spell lifesteal, this can become a potent way to regenerate health, potentially surpassing a Heart of Tarrasque icon.png Heart of Tarrasque. However, it is mitigated by both magic resistance and spell immunity of enemies.
  • Assault Cuirass icon.png Assault Cuirass adds physical staying power when Primal Beast's abilities are on cooldown, via additional armor and attack speed.

  • The Primal Beast first debuted in Aghanim's Labyrinth: The Continuum Conundrum as the event's final boss, appearing several months before he was released as a playable hero.
  • The Primal Beast wears three skulls on the "barding" that he wears as a sign of his previous imprisonment, possibly as trophies.
    • Connected to one of his back-plates is the skull of what appears to be a Slithereen, Slardar minimap icon.png Slardar's race.
    • Shackled to his left leg is the skull of what appears to be a rhino's resembling that of Frull's, the Shopkeeper's trusty beast of burden. Often mistaken for Magnus minimap icon.png Magnus' skull, the longer skull and the hole in its horn where her ring is supposed to be is proof that this is indeed Frull's skull, two features that Magnus lacks.
    • On his right shoulder is a another rhinolike skull. This one may or may not be a Magnoceroi skull.
