The Frenzyheart Tribe is one of two reputations available to players in Sholazar Basin. Sholazar Basin is a Northrend Zone, players must own the Wrath of the Lich King expansion in order to enter Northrend. The Main hub of the Frenzyheart Tribe is "Frenzyheart Hill".
The Frenzyheart Tribe is at war with The Oracles, the second faction found in Sholazar Basin. In order to begin raising your Frenzyheart Tribe Reputation you must first complete "The Part-time Hunter" quest and accept the quest from the Frenzyheart nearby
Raising Your Reputation
Raising your reputation with the Frenzyheart Tribe requires you to complete any of the 3 dailies available to you every day. Each of the dailies gives a different amount of reputation and will alternate almost every day. Below is a list of each of these dailies
Chicken Party (This daily never changes)
Capture 12 Chickens - 500 reputation
The Second Daily Will Be One Of These Three (700 Reputation each)
Tools of War
Secret Strength of the Frenzyheart
The Final Daily Will Be One Of These Four (500 Reputation)
A Hero's Headgear
Rejek: First Blood
Strength of the Tempest
The Heartblood's Strength
If you complete every single one of these dailies you will be awarded an Achievement. Of course you don't need to complete them all in one day, but over the course of your Frenzyheart career, so to speak.
Switching Your Faction
Players can Switch between their Frenzyheart and Oracles faction at any time by killing Artruis the Heartless in Sholazar Basin. He is located in the cave right next to The Lifeblood Pillar. When changing your faction to The Oracles you will start at 0/12000 Honored.
NOTE: It is recommended that players raise the faction they don't want first. Then do the quest to switch their faction to the opposing one. Then you will raise the faction you actually want to keep next and you'll be able to keep it forever and ever.
Additional Note: I recommend players raise Frenzyheart first then ditch it for The Oracles. The Oracles rewards you with an egg at revered that can hatch into many different goodies. This being the main reason you will want to keep this faction.
Final Note: If you do each of the 3 dailies available to you each and every day it will take 20 days for you to reach exalted with the faction.
