These are Glitches, specifically Brands, Glitches starts on p184 of Demon the Descent
Glitches can emerge from two primary sources: Primum
and Cover. Changes in either of these qualities cause them
manifest. Glitches fall into one of two categories: transient
or permanent. Transient glitches last only a short while (as
dictated by the demon’s Primum), while permanent ones
endure indefinitely.
Causes of Transient Glitches
- Succeeding on a compromise roll (optional)
- Dramatic failure during Installation (p. 188)
- Going loud (p. 195)
- Use the demon’s “loud” Primum rating, 10, when
determining the type, severity, and duration of this glitch.
Causes of Permanent Glitches
- Primum increases or decreases
- Failure or dramatic failure on a compromise roll
(optional)
