Battle Raptor/Pre 1.3

Overview
The Battle Raptor is the first animal listed in the Animal Trainer. To create the animal, you will need five teeth. However, its healing also requires a rare tooth, so be aware and consider healing it when its health gets low.

The raptor is arguably the best animal to train, due to its high damage and accuracy, and its range. It can still attack from behind units, unlike the Imperial Boar or the War Mammoth. Plus, it is cheaper than its counterparts.

Additionally, you will need a Raptor Ranch to train raptors. You will also receive one for the cost of five teeth (no trainer necessary) in a higher-level mission.
