I played through the first scenario with Conan, Valaria and Balthus as the heroes, with Balthus taking Slasher as an alley.
The Heroes barely won, with the princess being carried out of the village in the nick of time. But the real story was Slasher. He personally took out 4 Pict hunters, a Pict Warrior AND the Giant Snake.
He was awesome in the story "Beyond the Black River" and he's awesome in this game.
