NOTE: THIS SOLUTION IS FOR WARRIORS
Before I show you warriors how to beat the rabid bear, let me give you the background info:
Quite personally, this is a horrifically biased quest that is nearly impossible to do using a warrior. The club you wield does only 15-15 damage and even using standard PvP builds, you're unable to do enough damage to kill that bloody bear.
Here's why it's so damn difficult:
Natural regeneration
Spamming of Troll Ungent
Dolyak Signet
Defy Pain
Even if you get him down to half HP, he uses his utilities to get back to full or near full health. It was extremely frustrating fighting this abomination, and I feel it's fruitless trying to kill him using a hammer build.
So here's my suggestion.
1a. Set up a build using both ripostes (deadly and regular) along with disrupting and savage slash (since ungent has a faster recharge than one of these skills). Use a form of adren gain such as auspicious parry or anything else of your choice.
1b. A must for this build is "Finish Him!" or something that deals high spike damage. This will be your last move.
2. Put the Club of Bears into your second weapon set.
3a. When you start the battle, use your sword and shield. Interrupt his ungents and keep spamming ripostes. If you take too much damage from his leviathan sweep, use healing signet.
3b. When the bear is almost dead, quickly switch to your club and use "Finish Him!". The resulting damage and deep wound should finish him off, allowing you to take the victory.
Remember, you MUST have the club equipped before using your spike skill, or you'll LOSE the battle.
I hope this saves a lot of frustration for you guys. Please note I was rank 3 upon using the PvE Norn skill.
