Harmonisers are used to attune ebb-users to one another, making it easier to calculate ebb effects affecting each other. They come with a factory setting keyed to all other harmonisers, but this setting can be changed to include only select users via a small investiture of flux. It is impossible to reset a harmoniser to its baseline setting once it has been individualised, though additional users may continue to be added to the private network.
A harmoniser takes the shape of a small crystal affixed to the throat area of the deathsuit.
A single harmoniser costs 500c.
+1 rank in all ebb abilities for effects specifically targeting the bearer of a second harmoniser, which is attuned to the user’s own harmoniser.
To attune two harmonisers both user’s have to spend 1 FLUX each on each of the devices.
