Sanity
This page explains how Sanity is handled in Delta Green.
Note
Sanity will be completely revised and automated as part of an upcoming system update.
SAN shows the Agent's current and maximum SAN if impacted or not by the unnatural skill. To roll for SAN click SAN:
An Agent who drops to 0 SAN is permanently removed from the player’s control. The Handler decides when that happens in play; sometimes it is immediate, such as when the Agent breaks down and refuses to re-engage with reality.
