Hutia

Located in The Jade Forest. Hutia must be reduced to 30% health before it can be tamed, and it periodically casts an interruptable heal. If you're high level it can be very hard to do this without killing it, so you should remove ALL of your gear, kill yourself and take resurrection sickness, then reduce its health slowly with punches. Unless you have an interrupt that causes no damage you may have to just put up with the heals.

In contrast, if you're low level you may find Hutia hits very hard, so kiting (and maybe help from a friend) is probably necessary. Use Concussive Shot to slow it, and interrupt its heals when possible.
