Oswaft language, also known as Maser voice-streams, served as both the means of communication and weaponry for the Oswaft species.
The language they used was intricate and exceptionally advanced, with communication achieved through the modulation of radio-frequency waves using their minds. These vacuum-adapted beings possessed the capability to transmit "picture-messages" designed to represent visual reality instead of abstract concepts.
Oswaft possessed the ability to utilize this communication method in the manifestation of maser bolts. They described this action as "shouting" towards their adversaries. The Oswaft had the power to obliterate Imperial fighters with a solitary "shout," and were also able to annihilate unshielded starships. Nevertheless, maser voice-streams typically proved ineffective when directed against capital ship shielding.
