"With little to no aggression, ZAYIN Abnormalities will cause the least harm to your Agents. Their damage tends to be minuscule, and they may have a positive effect on the employees."
- Manual
ZAYIN Abnormalities are the lowest and safest Risk Level to interact with, before 
TETH. Players tend to get them through the first days and mid-game, and on certain occasions during the late game. They aren't very threatening to the employees or the player, none of them can breach, but most of them can still deal damage through abilities or even trigger insta-kill effects, so one should still handle them with caution. These Abnormalities usually give positive effects and/or don't cause major consequences.

Trivia[]
- Don't Touch Me is only a
ZAYIN because it produces 0 (ZERO) PE-boxes due to its ability triggering when entering the containment room, luring the employee working on it to press the button, ending the work as soon as it started. - Army in Black being rated as ZAYIN in containment is probably related to how it seems to represent a safe Abnormality by being 'pink' in its own story, or to mislead players.
- ZAYIN is based from the Hebrew alphabet, the 7th letter of the same name (ז). Represents 'returning light.'
