Tall, slender and elegant, the Phantom is the largest known pattern of Eldar Titan. It is swift and agile in comparison to the lumbering behemoths of the Legio Titanicus, and is armed with some of the deadliest examples of Eldar weaponry.

Each Phantom is the pinnacle of Eldar warcraft. Linked to a wraithbone core containing the living spirit of its previous pilots, the single crewman of each Phantom Titan, known as a Steersman, is an Exarch dedicated to this aspect of warfare. Locked in a trance-like state, the Steersman’s consciousness merges with the spirit-sentience of the Titan, enabling the mighty war machine to react and manoeuvre with astonishing speed.

The Phantom Titan is most commonly armed with at least one immense Phantom Pulsar, a long range and rapid-firing energy weapon far superior to anything sanctioned by the Adeptus Mechanicus. The Phantom’s other primary weapon is often a Phantom D-Cannon; much larger and more powerful than similar technology used by the Cobra or Warp Hunter, it tears a seething warp-rift in the fabric of reality to engulf and utterly destroy its foe. As well as these primary weapons, the Phantom is armed with shoulder-mounted anti-aircraft and anti-personnel missile launchers as well as an additional heavy weapon; usually a long-barrelled Star Cannon or Pulse Laser. Adeptus Mechanicus logis-engines also record other primary weapons systems that have been encountered in the long history of conflict between the Imperium and the Eldar.

Errrr...why do you need a stat conversion for a bog standard Phantom Titan...?

To see if they're wrong. Choose applicable "they".

The Phantom, and the Eldar Titan Power Fist in particular, are possibly up for review. Further evidence against the Epic Stats makes this more likely.
