My first exploit post, I searched and didn't see anything related to this.
In the Barrens, by the Lushwater Oasis there is lvl 15-16 Oasis Snapjaws(turtles). When you tame one it has Bite(Rank 6)! Usually u can't teach a pet that till lvl 40. Ive tested this 3 times each time the turtle had it. This could be a very good 19 twink pet, bite does like 40-50 dmg and has only a 10sec cooldown.
And another tip, to make the turtle even better you can tame Kresh from WC and take Shell Sheild skill that he has, and teach it to your Oasis Snapjaw at lvl 20.
Hurry b4 this is fixed!
