Since rats benefit too from the commendations (and training)... how about a power bonus formula on bite?
These are giant rats... if you take a giant pouched rat as example, they can easily bit off a finger at baby age. But they´re smart... and growing stronger...
Some advanced bite techniques or at least strength bonus on bite seem adequate
Never noticed before... but are they supposed to have full inventory capabilities? I can imagine a rat sized backpack, but I cannot imagine a minigun magazine fitting in it...
(poor rat would have a hard time carrying anyway)
and while we´re at it... ninja training for rats? master splinter anyone?
