Takes reduced damage when facing away from enemies.
The enforcer at a local pub, Rigwarl's never failed to collect a tab. That is, until he met one tough customer from the north. For the first time in his life, Rigwarl felt the need to train. His Thorny Back deters attack while peppering foes with constant baarrage of Quill Sprays. From his nose he blows Thick Gobs of Snot, slowing and covering opponents in goo. When it comes to a fight, he really puts his back into it. With every volley and every Sneeze, Rigwarl works himself into a fury, adding rage to each blow as he goes on the Warpath in search of a rematch.

Bio

Rigwarl, the Bristleback

▶️ "It was a barkeep that got me into this mess. Yeah, I think I'll pay em a visit when this is done."

Lore:

Never one to turn his back on a fight, Rigwarl was known for battling the biggest, meanest scrappers he could get his hands on. Christened Bristleback by the drunken crowds, he waded into backroom brawls in every road tavern between Slom and Elze, until his exploits finally caught the eye of a barkeep in need of an enforcer. For a bit of brew, Bristleback was hired to collect tabs, keep the peace, and break the occasional leg or two (or five, in the case of one unfortunate web-hund).

After indulging in a night of merriment during which bodily harm was meted out in equal parts upon both delinquent patrons and his own liver, Bristleback finally met his match. "Your tusks offend me, sir," he was heard to drunkenly slur to one particularly large fellow from the northern wastes whose bill had come due. What followed was a fight for the ages. A dozen fighters jumped in. No stool was left unbroken, and in the end, the impossible happened: the tab went unpaid. Over the weeks that followed, Bristleback's wounds healed, and his quills grew back; but an enforcer's honor can be a prickly thing. He paid the tab from his own coin, vowing to track down this northerner and extract redemption. And then he did something he'd never done before: he actually trained, and in so doing made a startling discovery about himself. A smile peeled back from his teeth as he flexed his quills. Turning his back to a fight might be just the thing.

Having caught a cold while stuck in the snow, Bristleback turns it to his advantage.

Notes:

• The goo travels at a speed of 1000.

• Places one debuff on the enemy. This debuff gets stronger when it gets refreshed with successive casts.
  • A number on the icon shows how many times the debuff was refreshed, including the first cast.

• For how much bonus armor and movement speed Viscous Nasal Goo reduces up to 4 ( 7) stacks on each level, please refer to the chart below.
  • Reduces affected targets' armor by 8/10/12/14 ( 12.5/16/19.5/23) at max stack.
  • Reduces affected targets' movement speed by 27%/39%/51%/63% ( 36%/57%/78%/99%) at max stack.

• Treats creep-heroes as heroes.

• With Aghanim's Scepter, Viscous Nasal Goo loses its cast time and backswing. It still interrupts channeling abilities upon cast.
  • Viscous Nasal Goo still uses the same disjointable projectiles.
  • Does not target invisible, invulnerable and hidden units, or units inside the Fog of War within the radius.

Ability Draft Notes:

Toggling Autocast on swaps this ability out with Hairball. Their cooldowns are separate.

An enforcer's honor can be a prickly thing. So can his quills.

Notes:

• Interrupts Bristleback's channeling abilities upon cast.

• The quills spread at a speed of 2400 and take 0.29 seconds to reach maximum range.

• The quills do not form a ring. They affect every enemy within the expanding area of effect, so it cannot be avoided by blinking towards Bristleback.

• The effect is centered at the cast location, it does not follow Bristleback.

• Places one debuff on each hit enemy and a stack debuff on each cast on each hit enemy.
  • The first debuff shows the number of stack debuffs on the status icon. The stack debuffs are hidden.
  • The stacks' durations are independent from each other. Successive casts do not refresh previous stacks' durations.
  • With the current cooldown and stack duration, it can be stacked up to 5 times. To reach the damage cap, additional procs from Bristleback are required.
  • The damage cap is reached with 20/18/17/15 ( 12/12/11/10) stacks. So to reach it, 15/13/12/10 ( 7/7/6/5) passive casts are required (not considering cooldown reductions).

• Checks how many stacks units have first and deals damage based on that, and then increases the number of stacks. This means the first hit only deals the base damage.

• For how much damage Quill Spray deals with a certain amount of stack on each level (before reductions), please refer to the chart below.

Ability Draft Notes:

Quill Spray must be drafted as well for them to passively proc.

Turning his back to a fight might be just the thing.

Notes:

• A visual effect and sound plays whenever his back receives damage if Bristleback has learned Quill Spray.
  • Taking damage from the sides shows no effect.

• Applies generic incoming damage reduction on Bristleback. Stacks additively with other sources of generic incoming damage manipulation.
  • The reduction affects all damage Bristleback takes that is not flagged as HP removal.
  • When taking rear damage, his effective health increases by 19%/32%/47%/67%.
  • When taking side damage, his effective health increases by 9%/14%/19%/25%.

• Checks the damage source's current position and compares it to Bristleback's facing angle on each damage instance.
  • This means on damage over time effects (i.e. Liquid Fire), damage of an instance is only reduced when within the right angle.
  • Damage from Death Ward, Proximity Mines is reduced when facing away from them, since they are their own source.

• Passive Quill Sprays based on its current level proc when Bristleback's back (not sides) collectively takes 210 damage (after all reductions).
  • If Quill Spray is not learned, no quills are procced.
  • The damage counter considers the 3 damage types, but not HP Removal (e.g. Soul Ring) or the no-reflection flag (e.g. Blade Mail).
  • The damage counter has no time limit and only resets once a passive spray occurs.
  • Any exceeding damage is completely ignored, this means if an enemy deals an instance of 420 damage, the passive triggers only once.
  • These sprays are independent from the cooldown, they neither trigger the ability's cooldown, nor trigger Warpath, and work while on cooldown.
  • They do not cost mana or proc on-cast effects either.

Ability Draft Notes:

Viscous Nasal Goo must be drafted as well for it to get applied.

Requires drafting Quill Spray to be unlocked.
Toggling Autocast off swaps this ability out with Quill Spray. Their cooldowns are separate.

Notes:

• Requires Aghanim's Shard to be unlocked.

• The hairball travels at a speed of 1200.

• The Viscous Nasal Goo and Quill Spray released are based on the current level respectively.
  • If neither are leveled, the ball does nothing upon reaching the targeted area.
  • Checks for their level upon projectile impact.

• Once the hairball reaches the center of the area, every enemy within 700 radius gets targeted by Viscsous Nasal Goo.
  • Viscous Nasal Goo does not target invisible units or units inside the Fog of War.
  • At the same time, a Quill Spray is released. The second Quill Spray is released 0.1 seconds later.
  • Both Viscous Nasal Goo and Quill Spray notes fully apply.

• Since Quill Spray travels faster than Viscous Nasal Goo, the quills always hit enemies before the goo does, so the quills do not benefit from the armor reduction.

Death

'Temper, temper,' his mum always chided. But in a fight, a temper can come in handy.

Notes:

• Does not trigger on active item abilities, on abilities with 0 cooldown, or on abilities which do not trigger on-cast effects.
  • The passive Quill Spray procs of Bristleback do not trigger Warpath either.

• Bristleback's model size increases and more particles fly around him the more stacks he has.
  • This has no impact on his collision size.

• Grants regular flat bonus attack damage.

• Stacks up to 6/8/10 times, meaning it can give at most 150/240/350 ( 300/440/600) attack damage and 18%/32%/50% movement speed.

• Each stack has its own duration, successive spell casts do not refresh the duration of previous stacks.
  • Only the first cast's buff is visible in the HUD. This buff has a number on it, showing the current amount of stacks.

Recommended Items

Starting items:

• Tango keeps Bristleback healthy in lane.
• Enchanted Mango gives passive health regeneration and burst mana when needed.

Early game:

• Boots of Speed gives valuable movement speed.
• Ring of Health helps to sustain in the lane and builds into both Vanguard and Hood of Defiance.
• Soul Ring provides you with virtually unlimited mana and synergizes well with Ring of Health.
• Magic Wand keeps Bristleback in the fight, giving him a chance to potentially use up charges twice for very large amounts of healing, and every two charges will grant him enough mana for an extra Quill Spray or Viscous Nasal Goo.

Mid game:

• Phase Boots gives armor and further assists in Bristleback's ability to chase.
• Arcane Boots is a decent alternative to solve the mana issue Bristleback has in the early game. It can be disassemble later to build Lotus Orb and Boots of Travel.
• Vanguard is one of a few strong early to mid-game pickups on Bristleback. It is best against teams that have a large amount of physical damage. Note that the damage block is deducted from the full attack damage, before any damage reduction (such as from armor or the Bristleback ability) takes place. It builds into a Crimson Guard.
• Hood of Defiance, as opposed to Vanguard, is a much stronger choice when the enemies rather rely on magical damage. It upgrades into a Pipe of Insight or Eternal Shroud.
• Solar Crest provides survivability with armor and attributes. The mana regeneration also helps with casting spells.
• Aghanim's Scepter is a strong utility item on Bristleback, turning his Viscous Nasal Goo into an AoE slow and armor reduction with high cast range and no cast point. Bristleback will get a full Warpath stack and high damage output, allowing him to run at max movement speed at all times while having his damage increased considerably.

Late game:

• Lotus Orb further bolsters defense with armor and health regeneration. Echo Shell can also dispel silences that plague Bristleback, while reflecting many targeted spells back to enemy casters. The mana and mana regeneration also help him to continuously cast Viscous Nasal Goo and Quill Spray.
• Shiva's Guard is another large armor item, and it fixes any mana issues Bristleback can have. The active ability also gives Bristleback more presence in teamfights, damaging and slowing enemies in a huge area.
• Heart of Tarrasque grants a huge amount of health and gives you significant regeneration. It helps in siege situations, where you can soak up lots of damage and then wait a short time to be back at full health. The immense health boost allows Bristleback to use the passive Quill Spray to their full potential, as he can tank significantly more, retreat to heal up and then repeat.

Situational items:

• Blade Mail is a hybrid pickup of damage and defense. It is strong against teams with high amounts of burst damage, either causing the enemies to take the damage themselves as well, or forcing them to not use their burst damage, giving Bristleback some time to deal with them.
• Heaven's Halberd is a strong pickup if you're not the hardest carry on your team or the enemy team only has one physical damage dealer that it can be used on. The evasion, status resistance, and strength increase can add a lot to Bristleback's survivability.
• Crimson Guard is built off of a Vanguard, which is also a good item on Bristleback, and is an item any team should have if up against a physical damage heavy lineup.
• Pipe of Insight is built off of a Hood of Defiance, which is also a good item on Bristleback, and is an item any team should have one of if there are any dangerous nukers on the enemy team.
• Radiance is great on Bristleback if you can get it early in the game after a couple of items to tank up. This is basically a get-more-ahead item, as if you're hard to kill despite putting so much gold into an offensive item, it can be the best item to snowball the rest of the game by farming quickly and dealing massive area damage in teamfights. However, if you get this item at the cost of being tanky, this is a terrible item to pick up.
• Octarine Core increases his damage output by lowering Quill Spray's cooldown time.
• Assault Cuirass has amazing synergy with Bristleback, as it is one of the few items that can increase the damage of his Quill Spray. It also increases his and his team's tankiness against physical damage, and the attack speed greatly increases his attack damage output thanks to Warpath. It also is a great pickup if there are other carries on your team which rely on physical attacks.

Trivia

• In DotA, Bristleback's hero model was a quillboar, having a much more boar-like appearance. His loss of boar-like features in Dota 2 was likely made to distinguish him from the quillboar race in the Warcraft universe. [1] As well, his hero title shares the name of a large quillboar tribe in World of Warcraft. [2]
  • Beta information revealed that Bristleback's original name was supposedly to be "Bristlebog", probably to avoid conflict with the aforementioned Bristleback tribe in World of Warcraft.
  • According to an unused voice response, Bristleback was originally designed with tusks.
  • According to Lycan's response (▶️ A boar is a wolf's natural prey), one of Bristleback's early designs resembled a boar.
• A silhouette of what appears to be Skywrath Mage can be seen in Bristleback's splash artwork, seemingly still having a beta model/texture.
