I went into the breeders room and shut the door, slept and healed up before I could even
try to leave...we had 4 Rattkin Goons and 3 Rattkin Snipers waiting in our only path out.
It was a tough fight but being healed up and having all of our magical powers in the beginning of the fight really helped!
If you are only being attacked by the Rattkin Patrol & Rattkin Archers, consider yourself lucky!
Be prepared to have to fight something everytime you return to that area now that you've killed the breeders.
Best of Luck to you getting out and if you end up feeling like you need to restore the game prior to killing the breeders and up a level or two before going back, don't feel bad about it! Be happy your were smart enough to save just prior to getting into your predicament!
