I have added two more skills, one for the Orc and one for the Impanzee.
Stunning Block
The Orc got something similar to the "Shield Bash" as Mello Tonin mentioned at the Dwelvers forum. He got "Stunning Block", so when he manage to block an attack from an enemy he does it so good that the enemy gets stunned. This makes it more important for the Orc to have a shield with a high block chance.
Barrel Roll
The other skill that the Impanzee got was the "Barrel Roll - Tucks and rolls to nearest enemy stunning it briefly" as also mentioned by Mello.
It was hard getting a good screenshot of this, but here we see two Impanzees in action:
Skills tab added to the creature menu
I have also expanded the creature menu a little so that we now have a skills tab as seen here:
