Rigwarl, the Bristleback, is a melee strength hero famous for his array of synergistic, simplistic, and yet effective spells with low mana costs and cooldowns. Though each cast of his spells has relatively weak potency on its own, their instances have a cumulative effect, making the Bristleback quite deadly the longer he stays alive in a fight; this is directly reflected in his ultimate, Warpath, which powers up his movement and attack damage based on the number of spells he recently cast. He is able to increasingly slow his enemies down and reduce their armor with Viscous Nasal Goo and hit them with a barrage of Quill Sprays, making him an effective chaser when ganking enemies. His low strength gain makes him seem less tanky than most strength heroes at first glance, but his signature Bristleback passive substantially reduces all damage he takes from the sides and especially the rear, making him very difficult to bring down if he's facing away from his enemies. In the right hands, Bristleback is a powerful ganker in the early stages of the game, and a powerful hard carry in the later stages depending on how much farm he gets.
- 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.
- This is how much armor and movement speed Viscous Nasal Goo reduces with certain amount of stacks on each level:
- Level 1: 3.4/4.8/6.2/7.6 ( /9/10.4/11.8/13.2/14.6/16) armor & 23%/26%/29%/32% ( /35%/38%/41%/44%/47%/50%) movement
- Level 2: 3.9/5.8/7.7/9.6 ( /11.5/13.4/15.3/17.2/19.1/21) armor & 26%/32%/38%/44% ( /50%/56%/62%/68%/74%/80%) movement
- Level 3: 4.4/6.8/9.2/11.6 ( /14/16.4/18.8/21.2/23.6/26) armor & 29%/38%/47%/56% ( /65%/74%/83%/92%/101%/110%) movement
- Level 4: 4.9/7.8/10.7/13.6 ( /16.5/19.4/22.3/25.2/28.1/31) armor & 32%/44%/56%/68% ( /80%/92%/104%/116%/128%/140%) movement

- 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.

- The cap is reached with 19/17/16/15 ( 11/10/10/9) stacks. So to reach it, 14/12/11/10 ( 6/5/5/4) passive casts are required (not considering cooldown reductions).

- In DotA, Bristleback's hero model was a quillboar, having a much more boar-like appearance.

As well, his hero title shares the name of a large quillboar tribe in World of Warcraft.
