Although his spells seem very weak at first glance, Rigwarl is a bad hero to underestimate. Quill Spray, Viscous Nasal Goo, and Warpath all provide relatively small effects when used only once, but each ability stacks when cast multiple times. Enemies of the Bristleback will soon find themselves covered in goo and shredded by constant quill fire if they aren't careful. Quill Spray deals increasing damage with each cast on the same target, and due to its low cooldown and mana cost it can be very deadly over time. When Rigwarl sees that his enemies are sufficiently weakened, he can move in for the kill with Viscous Nasal Goo. This ability slows the target and reduces their armor, increasing the damage of Quill Spray and Bristleback's physical attack and making it impossible to escape. Furthermore, casting spells puts Bristleback on the Warpath, which increases his movement and attack speeds as he uses his abilities. Bristleback's signature skill, and where he gets his name, is his near invulnerability to attacks that strike his back. All attacks and spells that come from behind him will be heavily reduced and cause additional Quill Sprays. Engaging a strong Rigwarl who is facing away is almost always a pointless exercise.
One of the strongest heroes if played correctly
Awesome enemy chaser
Can tank one or two enemy heroes by himself for a short time
Squishy enemies can't even stand up to him
Quick cooldown on main skills
Somewhat mana starved early game
Not a great end game hero

Rigwarl is a semi-carry hero mostly. He should not take Mid-Lane by himself as he is primarily mele. My favorite with him is to take top lane and farm up to level 6, while harassing enemy heroes that get too greedy early on. Once you get 2nd rank Quill and 1st rank Goo, don't be afraid to chase after a enemy hero in your lane, and spam the goo and quills until they die. More often than not, the enemy hero will be caught off-guard and not know what hits them. Don't get too greedy though...get your kill then get back to safety.
Once you reach level 10, you can safely roam around along with a teammate, starting team fights and ganking enemy heroes cutting through the woods. Keep leveling the Goo and Quills to max, and pick up Warpath at the appropriate times.
For late game, you should follow the majority of your team's push and goo the first couple enemy heroes you see while trying to get close to quill them to death. Spam the goo over and over to help your team take enemy heroes out quickly.
If you find that you are not putting up good damage at end game, pick up Crystalis for some added damage.
