The most rare and expensive poly morph tome drop and for a reason. The bears that drop it are VASTLY spread out across the zone and getting one can mean hard farminh for a while. They also take a while to respawn so watch out. Getting one to drop can mean a staggering 48,000g, and on top of that compared to other pet farms and such, they have a much higher drop chance. Simply head over to dragonbligh ona mage character (class trial is perfect) and start the killing. Cross you fingers as there is an 0.4% chance to get one on each kill. Thats actually pretty high considering..
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
