Frightful Presence (Ex): This skeletal black dragon can unsettle foes within 210 feet with its mere presence whenever it attacks, charges, or flies overhead. Creatures with 4 or fewer HD become panicked for 4d6 rounds, while those with 5 to 21 HD become shaken for 4d6 rounds. A DC 23 Will save negates the effect and makes the creature immune to that dragon's frightful presence for 24 hours.

Keen Senses (Ex): A skeletal dragon sees four times as well as a human in low-light conditions and twice as well in normal light.

A skeletal black dragon possesses none of the craftiness it had in life. It merely attacks at its master has ordered. Its blindsense and keen senses make it an excellent guardian.

A skeletal black dragon takes on a new level of horror in undeath. Lizardfolk adepts and clerics often animate skeletal black dragons to protect their tribes.
