-# The Ice Cave (Eino)
-#
-#
-# Ice Cave is aimed to appear at somewhere in the middle game. It should be
-# fairly challenging, but also allow retreating. The entries shouldn't be out
-# of depth.
-#
-# Flavour: white colours, ice monsters, appropriate clouds.
-# The escape is at the start. The player can back away if s/he decides
-# some challenges are too much to handle.

+#

+# Flavour: white colours, ice monsters, appropriate clouds.

+# The escape is at the start. The player can back away if s/he decides

+# The destination vaults ############

+# Currently, there are five cave vaults (each of weight 6) and three

+# cavern vaults (each of weight 5).

+

+############################################################################

+# small caves

+#

+# All have the starting point next to the exit, so you can always retreat;

+# a middle point/area where there is some loot; and the end, where there is a

+# bigger challenge and some major loot. Ideally weaker characters attempt

+# to overcome the midpoint and then go back to dungeon, and strong characters

+# can try to clear the whole cave.

+

+# Foes: animals + frost giant & an ice statue.

+# Loot: heavy weapons and rC gear wearable by big races,

+#       plus some useful potions in the freezer.
