Special Abilities
Despair (Su) All creatures within a 30-foot radius that see a mummy must make a DC 16 Will save or be paralyzed by fear for 1d4 rounds. Whether or not the save is successful, that creature cannot be affected again by the same mummy's despair ability for 24 hours. This is a paralysis and a mind-affecting fear affect. The save DC is Charisma-based.

Description: As terrible as the process is for making a mummy, the creation of a Metal Muumy is far worse. The luckless victim chosen for this "honor" is killed like a game animal by the slashing of his throat while inverted that his blood may more readily leave the body and end his life. Then the braziers are lit and the metal the mummy is to be made of is melted. A cup is placed over the wound an the metal poured into it where it is magically sent under the skin which is left intact while the flesh is burned away leaving the metal in the exact shape of the corpse. The flimsy material that covered the skin during this process is scorched and burned in spots. Through these gaps in the fabric, the type of metal this mummy is made of may be see with a Perception Roll of 24 if it is looked for.
There are 5 types of metal used to create these monsters. Each has a slightly different set of attributes that modify the base values above.

Brass:
All the stats above apply to this base Metal Mummy. When awakened a Brass Mummy begins to heat up. When it is struck by any weapon, it's heat becomes searing and becomes hotter with every successful hit. The creature there after heats to where attacking it causes 2 HP per time it is hit.
