I was thinking of adding some other enemies to spice up the horde action- making it so they aren't just fighting hordes of kroot most of the time. This way there would be a phew special creatures within the horde, or another horde of kroot hounds.
This is what I've come up with for the Krootox
Remember that Bestial Creatures always pass survival tests in their natural environments. I'm not entirely sure, but is there already a Kroot hound profile made?
