VICTORY CONDITIONS
HEROES: The Heroes win the Scenario if before the end of Turn 8[1], they have either escaped with Princess Yasimina or Thulsa Doom is killed, and at least Conan and Subotai are still alive.
OVERLORD: The Overlord will win should the Heroes: Fail to steal Princess Yasimina; Valeria and Conan or Subotai are killed, or; Princess Yasimina dies before the end of Turn 8
May I suggest that if Valeria dies, the scenario is a draw, or the victory points for the heroes are reduced. If she survives, she’ll be present at the battle of the mounds, so in Scenario variant.
still not sure about this: Why should Yasmina be killed by the OL?
