Mangled bones are obtained when fighting the monsters or rummaging the barbarian skeleton found on the ground within the Ancient Cavern. With any type of logs, an axe, and a tinderbox, players can use it on the burnt space (pyre site) to make a pyre ship.

A sure way of getting mangled bones is by killing confused barbarians or lost barbarians, as they always drop them. Note that a bonecrusher will activate for these bones, giving the experience of normal bones.

Note: if rummaging a skeleton at least 2 slots must be free because of the random chance of finding an ancient page for my notes. If the player does not have enough slots free, the bones will "disintegrate". The chance of obtaining a Mangled Bone from a skeleton is 11/202.

Mangled bones also do not give the Prayer experience bonus that chewed bones give.

When burned in a barbarian funeral boat during the Barbarian Training will release a level 166 ferocious barbarian spirit, which after killing will drop a reward at its feet. However, players cannot receive a dragon full helmet, which can only be obtained from chewed bone pyre ships or as a drop from mithril dragons.

Mangled Bones will NOT work for barbarian training miniquest.
