Displacer Dragon (3.5e Monster)

"It is done with our world at last. All that remains for us are ashes, but from ashes perhaps a new world can emerge.  And may the Gods have mercy upon whatever place the thing finally decides to land upon."

After a millennium a Displacer Drake begins to become it's final form, the Displacer Dragon. Ribbons of spiny flesh hundreds of feet long, they're claws are now at the end of 4 long tentacle like appendages. They leave worlds after scavenging them of life, and fly to others to spread their kind. Displacer Dragons usually speak Common, Sylvan, Draconic, and at least 4 other languages. They are rare in the extreme, and only 3 such beings are currently known. What isn't known are their goals, though some say they effectively wish to travel to the Far Realm and set themselves up as deities of a sort.

Combat
Displacer Dragons will usually lurk invisibly until a sizable prey appears, then decloak and move in for the kill, blasting away with their Fetid Breath. The Tail Lash is usually reserved for the most troublesome opponents.

Fetid Breath: Once every 1d4 rounds the Displacer Dragon can breathe a 300' Cone of poisonous vapor. The poisons are a byproduct of their odd metabolism, and how they rid their body of toxins (they effectively have no liver or kidneys). Any creature in the Cone must make a DC 78 Reflex Save or take 2d6 temporary Int and Wisdom damage. Additionally they must make an additional DC 78 Fortitude Save each round for 3d6 rounds, or take a cumulative -2 penalty to Listen, Spot, and Search checks each round. When all 3 skills have a negative penalty the Displacer Dragon is effectively invisible to the victim. The penalty lessens by 4 points a day until normal (a Greater Restoration spell negates the penalties immediately). Save DC is Constitution Based.

Frightful Presence : Whenever the Displacer Dragon attacks, charges, or flies overhead anything within 700' has to make a DC 77 Willpower Save (Save DC is Charisma Based) if it has fewer Hit Dice than the Dragon. If they fail they are Panicked for 2d6 rounds, if they succeed they are Shaken for 2d6 rounds and immune to this Dragon's Frightful Presence for 24 hours.

Distortion Field : Effectively the Displacer Dragon is surrounded by an Anti-Magic Field that only works against Illusion spells or effects. They cannot be cast within 30' of a Displacer Drake. At will it may drop this Field to become Invisible instead (as per the spell) until it attacks or restores the Distortion Field.

Spiny: The Displacer Dragon is now covered in many small sharp barbs hidden in it's hide (much like a shark). Anything attempting to grapple the Dragon takes it's own Strength modifier in damage each round it maintains the grapple. If the Displacer Dragon grapples something it does +1d6 damage with a successful grapple.

Unnatural Sharpness: The critical threat range of all the Displacer Dragons natural weapons is increased by 1.

Spell-Like Abilities : Dimensional Lock, Greater Teleport, Land Womb, Scry Trap 3/day. Caster Level 33rd.

Warp Field : Displacer Dragons may warp time and space around them, effectively traveling through space as quickly as any ship (we'll assume this means roughly light speed). Exact effects are up to the DM depending on how he handles space travel in his campaign (which is a nice way of saying I don't know of any official space travel rules, and I don't have the time to make any).

Displacement : Any melee or ranged attack targeting the Displacer Dragon has a 50% chance of missing unless the attacker has some means of locating them other than sight. See Invisibility doesn't negate this but True Seeing does.

Resistance to Ranged Attacks : Displacer Dragons have a +8 Resistance Bonus on Saves against ranged magical attacks that specifically target them (except for ranged touch attacks).

Wide Angle Vision: Due to it's many eyes a Displacer Dragon cannot be flanked, and it has a +4 Racial Bonus on Spot and Search checks.

Flight: Displacer Dragons levitate by unknown means (they have no wings). For all intents and purposes they have a permanent Feather Fall effect on their person at all times.

Skills: Displacer Dragons get a +8 Racial Bonus to Hide and Swim checks. They may always Take 10 on a Swim check, even if threatened or endangered. They may use the Run action while swimming in a straight line.

Life Cycle: After a 1000 years or so of life a Displacer Drake will pupate for 4 months, after which it will emerge as a Displacer Dragon, and leave for the stars to spread its species to other worlds.

Colossal+: The Displacer Dragon has double the usual Size Bonuses/Penalties due to size.

Immortal: The Displacer Fish that lives to see Dragon status effectively becomes Immortal. It is immune to aging, even by magic. It is also immune to poison, paralysis, polymorph, sleep effects, fear or morale effects, fatigue/exhaustion, cold damage and disease. They are immune to extremes of temperature that occur naturally, but are still capable of being effected by magical attacks such as fire if they are powerful enough. Likewise it is immune to vacuum, or the extreme pressures of the ocean depths. It does not sleep or breathe anymore, but must still eat.
