Bristleback
Rigwarl was never one to show his back to a foe. Known as the 'Bristleback Master' by drunken brawlers from the Kingdoms of Slom to Ezer, he intervened in countless backyard brawls for a few coins and drinks. After a legendary bar fight that ended with an unpaid bill, Rigwarl discovered that facing away in combat might actually be perfect. Now he dives into battles without worrying about damage from behind and sides, spraying damaging quills and slowing nasal goo at enemies.

Hero Overview
Bristleback is a formidable tank and sustained damage dealer who excels in prolonged fights. His unique damage reduction mechanic when facing away from enemies, combined with the stacking damage from Quill Spray, makes him incredibly difficult to kill while dealing significant damage over time.
Bristleback's gameplay centers on positioning to maximize his damage reduction while constantly casting spells to build Warpath stacks. He excels at whittling down enemies through repeated Quill Spray applications and Viscous Nasal Goo armor reduction. His tankiness allows him to absorb massive damage while slowly but surely overwhelming opponents.

- Struggles against heroes with high armor or physical immunity
Ability Analysis

Viscous Nasal Goo
Target UnitCovers a target enemy in snot, slowing their movement and attack speed, and reducing their armor.
Notes: Spammable slow and armor reduction. Works on Roshan, making Bristleback excellent for early Roshan attempts. Stacks up to 4 times, each stack increasing the slow duration. Use it to chase down enemies or reduce their armor for your team.

Quill Spray
ActiveSprays quills in a cone around Bristleback, dealing damage to all enemies in the area. Each cast applies a stack that increases the damage of subsequent casts.
Notes: Your primary damage source. Physical damage that ignores magic immunity. Can be set to auto-cast to spam automatically. Excellent for farming stacked camps - you can kill ancients without even looking at them.

Bristleback
PassiveBristleback takes reduced damage from attacks and spells that hit his rear or sides. When damage taken from the rear exceeds a threshold, he automatically sprays quills behind him.
Notes: The core of your survivability. Always try to face away from enemies when taking damage. The passive also triggers Quill Spray automatically when taking enough damage from behind, adding to your damage output.

Warpath
PassiveWhenever Bristleback casts a spell, he gains a stack that provides bonus movement speed and attack damage.
Notes: Stacks up to 5 times, each stack providing significant movement and attack speed bonuses. Lasts 10 seconds and refreshes duration with each cast. The key to your damage output - always keep stacks up during fights.

Warpath (Aghanim's Scepter)
ActiveBristleback locks his facing direction, allowing him to cast spells and items without turning, while gaining bonus damage and reduced vision range.
Notes: Game-changing active ability. Locks your facing direction, making you immune to forced turning effects. You can cast spells and use items like Blink Dagger without turning. Each Quill Spray from this state adds a Warpath stack.

Counter Guide
Good With
Bristleback synergizes well with heroes who can capitalize on his tankiness and ability to prolong fights. Axe creates a double-tank frontline that's incredibly difficult to break through. Legion Commander benefits from Bristleback's ability to force enemies to stay and fight, setting up perfect Duel opportunities. Dazzle provides armor reduction through Weave and healing through Shadow Wave, complementing Bristleback's sustained damage approach. Crystal Maiden offers mana regeneration that enables constant spell spamming for Warpath stacks. Winter Wyvern and Oracle provide additional survivability and utility, allowing Bristleback to dive even deeper. The key is heroes who either enhance tankiness or benefit from enemies being forced to stay in prolonged engagements.
Bad Against
Bristleback struggles against heroes who can bypass his defensive mechanics or exploit his weaknesses. Viper applies break through Viper Strike, completely disabling Bristleback's damage reduction passive. Axe forces Bristleback to face him with Berserker's Call, negating his directional defense. Phantom Assassin with high burst physical damage can overwhelm even Bristleback's tankiness. Nyx Assassin can burn mana with Mana Burn and spike with Vendetta, preventing sustained spell spamming. Silver Edge carriers can break Bristleback's passive, making him extremely vulnerable. Heroes with forced positioning like Batrider or Beastmaster can drag Bristleback into unfavorable positions. Dispel-heavy heroes like Abaddon can remove Nasal Goo stacks quickly. The pattern shows heroes with break effects, high physical burst, or strong dispels pose the greatest threats.
Good Against
Bristleback dominates heroes who rely on multiple units, sustained damage, or cannot handle prolonged fights. Illusion heroes like Phantom Lancer and Naga Siren suffer immensely as Quill Spray tears through illusions while stacking damage. Summon-based heroes such as Broodmother, Visage, and Beastmaster trigger countless Quill Sprays from their summoned units. Squishy carries without escape mechanisms like Sniper and Drow Ranger get worn down by constant Nasal Goo and Quill Spray stacking. Melee heroes who need to stay in close combat like Ursa and Sven trigger repeated Bristleback procs while taking stacking damage. Heroes without strong burst struggle to overcome Bristleback's tankiness and sustain. Low mobility heroes get chased down easily with Warpath movement speed and Nasal Goo slow. Bristleback thrives against anyone who can't quickly burst him down or escape his relentless pressure.
