We changed the number of players participating during the campaign, so the quests shall not be understood as "the wisdom for balancing" or anything - it's just what we used.
I start right away, with the first quest; The Frozen Horror Quest 1, Xanon Pass
Layout (same as original py phoenix)
Quest 1 - A quest for one beginner Barbarian and four Mercenaries
Xanon Pass
Good luck, Barbarian, on this, your first of three trials! Servants of the Frozen Horror have overrun the fortress that guards Xanon Pass. This is the only pass over the Cyberian Range, which you must cross to reach Ice Mountain. An iron door is your entry into the fortress. You must find the wooden exit door that leads out to the far side of the pass
Notes:
Four mercenaries offer their help to the Barbarian; one of each kind. Place them next to the Barbarian, right before she opens the iron quest entry door.
A: If the Barbarian searches for treasure in this room, 75 Gold Coins are found in the chest.
B: The evil Crossbowman does not move but fires his crossbow at the Barbarian once during each of Zargon's turns until the Barbarian reaches him. If the Barbarian moves next to the Crossbowman and attacks, the Crossbowman surrenders immediately, offering his crossbow in exchange for his life. The Crossbowman then runs away. The Barbarian should take the equipment card.
C: If the Barbarian searches for treasure in the room, a shield is found in the tomb. Take the matching equipment card.
D: If the Barbarian searches for treasure in this room, a longsword is found in the weapons rack. Take the matching equipment card.
Wandering Monster: two Skeletons
In total, the mercenaries and the Barbarian together lost 14 Body Points; and that's with the additional attacks that come from the mercenaries. How a single Barbarian is supposed to survive, I don't know.
During the game, clmckay and kitch discussed that the northeast sector likely doesn't contain the exit as it is surrounded by a hallway; so that part is avoidable damage.
Maybe that's the solution, just don't go everywhere. On the other hand, if you take the minimum path, you won't have enough gold to buy mercenaries and survive part II.
