Tacet Discords are sentient beings formed by the residual chaotic frequency energy. They have yellow Tacet Cores on their bodies, and amorphous, ever-changing shape. They instinctly feed on other frequencies to maintain stability and evolve.
These creatures mimic the abilities, shapes, and behaviors of others and are influenced by the types of frequencies they consume.
There are 5 known Tacet Discord mimicry types listed on an in-game document: Whisperin, Howler, Tranquilite, Clamorling, and Staticoid. SOUNDS!
To learn these, you can do the following:
Read Tacet Core Drop descriptions, observe the shape of Tacet Core, observe TD behavior/shape (do they mimic a human trait/role, do they behave like an animal, do they have mechanical parts, do they resemble other things on the planet).
For clarity, when I use the term Tacet Core from now on, I am referring to the distinct ones you can see on their bodies. When I say Tacet Core Drop, I am referring to the items in your inventory. No drops in-game for the other 3 mimicry types that aren't Whisperin and Howler.
These Tacet Discords stand on two feet, can mimic warriors, use instruments, etc. Human traits!
Example: You have Crownless, who mimics a Knight but can never grasp the concept of chivalry and Knighthood, rendering it a ghost of endless warfare.
Whisperin Tacet Discords have a Tacet Core that resemble a star.
Here are the descriptions of the low frequency, middle frequency, and high frequency Whisperin Tacet Core Drops.
"Broken star", "Frequency Energy aligns with the hearing range of normal people".
In the Act about Qichi Village, you will come across this Tick Tack Whisperin Tacet Discord, who repeats the words of a young child from village because it absorbed their frequencies.
