Mountain giants are rarely encountered outside their lair -- a huge
cavern cawed out of the heart of a rocky mountain. In addition to
their normal tongue, they can all speak the ogre language.

Like their cousins the hill giants they can hurl rocks from 1" to 20"
distance, inflicting 2-16 hit points of damage if they hit. They are
able to catch similar missiles 30% of the time. <Grenade-Like Missiles: Boulders>

In melee they strike
with huge clubs, inflicting 4-40 hit points of damage.

The mountain giant can summon and control other monsters -
usually (70%) 6-15 ogres, but sometimes (20%) 4-9 trolls or even
(10%) 1-4 hill giants. If a mountain giant is encountered in its lair, it
is 75% probable that these creatures will be there, acting as servants
and guards.

Giantesses and young mountain giants are rarely encountered - if
four mountain giants are encountered in their lair, there will be in
addition one female and one young giant (each has hit dice of 8+ 1-2
and 1 attack doing 2-16 hit points of damage; otherwise mountain
giants encountered will always be adult males.

Mountain giants have light tan to light reddish-brown skin and dress
in rough hides or skins, as do the hill giants.
