If you spend at least 1 minute observing or interacting with another creature outside combat, you can learn certain information about its physiology. The Game Master reveals to you two of the following characteristics of your choice:
- Any one ability score
- Armor Class
- Current hit points
- Resistances (if any)
- Immunities (if any)
- Vulnerabilities (if any)
Alternatively, you can spend 1 minute observing a corpse. After 1 minute, you determine the cause of death.
