Five new Pet Battle achievements were added to the WoD Alpha, however they may only be for testing purposes and are subject to change as indicated by their names. [source]
- [TEST] Beast Beat-down - Finish a battle with a Beast ability.
- [TEST] Hydraulics - Win a pet battle with an Aquatic and a Mechanical pet on your team. 5 points.
- [TEST] If One Is Good... - Win a battle with 3 Vengeful Porcupette pets
- [TEST] Survivalist - Win with three pets alive!
- [TEST] We've Got a Bleeder! - Win a pet battle with Bleeding as the final damage.
We'll have to wait and see whether or not these achievements stick around for the release of the expansion. More might be in store for us, but let's just hope there isn't a challenge that involves using three Darkmoon Rabbits or three Viscous Horrors to win a battle!
Two new pets were also discovered, the Grovestrider Hatchling and Lifelike Mechanical Frostboar. [source]
List of all WoD Alpha datamined pets
It's unclear where the Grovestrider Hatchling will come from, but the Lifelike Mechanical Frostboar is currently listed as an engineering recipe (requiring skill level 700).
To possibly accompany our new piggy-pet, a new Battle Pet ability was added, Pig Out. There aren't any battle pets assigned to this ability yet, but it sounds as if it was made for a hungry hog!
Last but not least, two new Battle-Stones were found lurking in the WoD Alpha, Training Beast Battle-Stone of Testing and Training Battle-Stone of Testing.
There are currently only the two listed above, and as their name suggests, they are subject to change. With all things in testing phases, these stones may not make it into the expansion, but it will be interesting if they do.
The Training Battle-Stones are different than the stones that currently exist — instead of increasing the quality upon use on the selected pet, these new stones raise your pet's level by one. They are also of epic quality and are Bind on Pick Up.
We look forward to learning more about these "rare candies" as well as all pet-related additions to the WoD Alpha.
