# V for Volcano!
#
# A combined effort of ideas, execution and tweaking by Jude, dpeg, and Zaba!
###
#
# i. Threats
#
# Initial threat is the volcano itself; while there is quite a
# delay between explosions, the flame clouds are quite powerful
# and cover quite a large area; this could kill an early level
# character easily, so beware!
#
# Loot-guard threats are defined in the fiery_guardians function.
# Please see the comments there for explanations, and lists of
# possible threats.
#
# Extra threats will be listed as MONS: lines.
#
# ii. Loot
#
# All volcanoes have a combination of the following items, though
# the amounts of each usually vary. In addition, they also have
# whatever armour or weapons have been created for the monsters that
# populate the level.
#
#   Fire resistance ego armour (any type of armour; this also
#                               includes dragon armour, which is not
#                               given extra rF+)
#   Flaming ego weapons        (a selection of high-damage weapons)
#   Gold
#   "Good" potions with fire themes (see setup_loot() for the list)
#
# In addition, some volcanos have extra items taken from:
#   "Random item"
#   "Bad items"                (see setup_loot() for the list)
#   "Fruit"                    (only in volano_6)
#
# See setup_loot() for more information.
