So, lets say we give an owlbear cub a headband (or collar?) of intellect. That headband has the skill linguistics with common and a couple other languages associated.
How does this affect training said owlbear? It would be as intelligent as a chimera (int 4) which has the entry:
"They are too stupid and belligerent to acquire followers, though sometimes a tribe of kobolds might give them offerings. Conversely, they are just intelligent and stubborn enough that they make poor pets, and only a significantly more powerful creature can keep them submissive. They may form equal partnerships with a respectful humanoid or similar creature, and even consent to be used as a mount."
Owlbears are Neutral while chimera are chaotic evil. So there is that. But would it still cost 2000GP to train and raise this owlbear cub? Would we even use the handle animal skill since it is now intelligent and can speak?
