Alien Race that communicates via pheromones - how to stat it?
 

I'm building an alien race (let's call it alpha, as a placeholder name) that communicates via pheromones within its members and use a device to communicate with other races.
Without the device, Alphas are completely mute when talking to other races.

I stated them like:

1. Discriminatory Smell [15]

So they can smell each other pheromones and communicate.
But I keep looking at it and thinking that something is missing.

1. Cannot Speak (mitigator -60%) (-25*0,4) [-10]

And this to represent Alphas inability to talk with other species.

So, anyone can give me a hand here?

This is essentially no different than a race that can only see with Infravision or that can only hear and communicate with Ultrasonic Speech. Canonically, having an alternate sense is a 0 point feature if it's their only form of that kind of sense.

If they have Discriminatory Smell on top of being able to smell each other's pheromones then it's an advantage. If the only form of "special" smelling they have is to smell each others pheromones then it's not an advantage.

Under no circumstances is Mute appropriate if they can communicate normally amongst themselves, any more than it would be appropriate to give a race with Ultrasonic Speech Mute and Deaf.

Now, realistically communicating via pheromones would have some serious drawbacks, not the least of which is a slow communication rate and limited physical range (though the ability to layer speech over time could have some advantages). That would probably be worth points similar to having a speech impediment such as Stuttering. Of course, realistically no race could communicate complex thoughts via pheromones, it's just not an effective way of communicating at all.

What your missing there is a method to speak. Discriminatory Smell is more akin to the ability to hear.

For that I would go with telecommunication.
EDIT: Just checked several books and could not find this in 4E. I have thought about this a few times but never gotten around to writing a race up with it.
I would go with 10 points, its fairly short range but you could leave messages as if writing.

If they are not the main or reference race (to borrow a term from GURPS Social Engineering) I would disagree on the "under no Circumstances" part.
Also if you had them but telecommunication I would allow Mute since voice has a lot of advantages.

No circumstances?

The same can be said of speech and sight which can be enhanced by technological upgrades. "Writing" is certainly possible by perfuming an object meant to carry such marks.

Also communicating by smell is not necessarily the only mode of communication.

Yep, telecommunication sounds right. I wish we'd get some sort of pyramid article giving actual guidelines for telecommunication that's not one of the basic types given. It doesn't come up much, but when it does, you really want it.

I don't know if 5 or 10 is the right amount for this telecommunication. Its not secure, and its quite close range. It does stick around, which is worth something. I lean towards 5 rather than 10. Still if you ever need to modify it, it gets sticky: cross-world pheromone communication is quite cheap with this build.

I don't think simply adding to mute to a creature who can pheromone but not speak in any case where the campaign isn't very human-centric. Though I suppose the voice synthesizer is reasonably appropriate. Ultra tech does funny things to trait values.

Yeah its a tough call. 5 seems fair but on the other hand you could leave messages on trees without needing writing materials.
Kind of like ant trails. They can degrade of course but a lot of what would mess with smell would ruin paper.
I would like to see an article like you describe, I have created a few new Telecommunication advantages for my fantasy settings. Dreamspeaking being the most broadly useful one.

Paper is hardly the only way to leave lasting messages. Arranging rocks and sticks, scratching or carving into surfaces, paint, embossing, embroidery...

5 points. Compare to radio which has a 10-mile radius and is worth 10 points.
