Ok, I have reached the final boss and depending on the way you manage the dialogue with him, an additional dragon will join the battle. I have tried defeating them both without having any of my characters killed (because I dislike the Xp loss when I revive them) but it's pretty hard. I just want to know if the black dragon will wait for me back near the exit if he doesn't join the battle with the green dragon? If that is the case, I better fight each of them separately.
Thanks in advance!
