This bone naga's master is still alive and has ordered it to guard the underground chambers where it performs magical research.

The bone naga always scans the minds of intruders to determine their strengths and weaknesses before joining combat. It often begins by trying to intimidate its enemies with telepathic taunts. Thereafter, it resorts to spellcasting to soften up the more powerful-looking opponents. When it finally enters melee; it focuses its attacks on living opponents rather than undead or constructs, since the living are susceptible to its poison.

This example uses a 6th-level dark naga sorcerer as the base creature. Created by a rival hundred of years ago as a guard, this bone naga despises both its master and its condition.

A bone naga is a skeletal undead creature created from a naga by a spellcaster (usually of its own race). A create undead spell can produce a bone naga from any naga subject with fewer Hit Dice than the creator.

A bone naga looks like a serpentine skeleton and typically measures about 12 feet long. Its skull bears an eerie resemblance to that of a human, except that it sports long fangs. A cold, cruel light burns in the creature's eye sockets, giving it an air of unspeakable hatred and malice. Its tail ends in a vicious bone stinger.

Though it despises servitude, a bone naga unswervingly obeys its creator, attacking even other nagas if so commanded. Should its master die, the bone naga becomes free-willed and can choose its own destiny.

Augmented Subtype

A creature receives this subtype whenever something happens to change its original type. Some creatures (those with an inherited template) are born with this subtype; others acquire it when they take on an acquired template. The augmented subtype is always paired with the creature's original type. For example, a wizard's raven familiar is a magical beast (augmented animal). A creature with the augmented subtype usually has the traits of its current type, but the features of its original type. For example, a wizard's raven familiar has an animal's features and the traits of a magical beast.
