Statting up a Dullahan

[Varyon]

I realize things have moved on to Duplication, but...

Not only is it always at the head, but this is the only place the character's senses (other than Touch) are located. This also requires placing a highly-vulnerable (it can't defend itself, and it's rather easy to target the Skull, for x4 injury) body part away from the reach of the body, which is problematic. I'd say the cost for this - even considering the boosted range - would be [10], making it functionally a net total -80% Limitation, and I wouldn't be too argumentative if someone placed it at [5].

It's a Ranged Headbutt, really (you'd have to hit with the least aerodynamic part of the head to deliver a bite). The fact you need to throw your most vulnerable bit calls for a significant discount. Considering all that - and the fact the character already has a headbutt attack, this is just putting Ranged on it - I'd eyeball it as a Perk, maybe [2].

This is covered by your Clairsentience, above.

Does the dullahan have a Neck hit location? If not, this is simply IT (No Neck) at full cost (being able to be suffocated by someone holding their hand over your mouth is a function of lacking Doesn't Breathe). If so, no trait is needed. If your dullahans have a Neck that can be choked, but is treated as a Torso hit for purposes of Injury, then your build would be correct. Decapitation is just a special effect of a Neck wound that kills you.

Seems fair.

Perhaps No Legs (Portable) [-30], but applied only to the Head. The Head is right around 10% of the character's surface area, so [-3] doesn't seem too inappropriate.

Included as part of my interpretation of Clairsentience.

Compare a character with normal Duplication (where death of the dupe means sympathetic Injury and loss of the Advantage) to one with this Limitation and Extra Life. At -60%, the character is saving [21] on Duplication and paying [25] for Extra Life. For a net cost of [4], the character gets a "get out of death free" card, which is a pretty serious discount.

What you're really looking at is something more akin to Vulnerability x7 (Sympathetic Injury), where Sympathetic Injury is really more rare than Rare. Vulnerability x7 (everything) would be [-125] (by symmetry with IT:DR), against a Rare threat it would be [-25], and against this Ultra-Rare threat it would probably be something like [-12.5], which I'd round down to [-10].

If you want to bump up "only your dupe" to -80%, I personally wouldn't object since normally Telesend w/racial would be your entire species (humans, for example).

Agreed on the first. For the second, One Person Only is canonically -80% (PU8:5), so there's a good reason to take that instead of Racial.

As for the fact the dupes share senses, that's worth at least a Perk, being roughly comparable to Teamwork. Special Rapport wouldn't be entirely out of the question, however.
