Is there any way to avoid killing Rex?
Despite popular myth, there is. But I don’t recommend it. Rex’ll start a fight, but don’t attack. Run Party North. Then use Climb North. Disband West a character with Climb and have him rescue Jackie. Keep evading with the other party. Return the party with Jackie to the rest of the party. Then leave. The dog is untouched. And unless you’ve got some good armor, your party is trashed. But you’ve got Jackie and Rex lives! To tell the truth, just beat the snot out of Rex, it doesn’t matter. I just wanted to prove that it IS possible to save Jackie without killing the dog.
