A condition is a temporary game state. The definition of a condition says how it affects its recipient, and various rules define how to end a condition. This glossary defines these conditions:
| Blinded | Grappled | Poisoned |
| Charmed | Incapacitated | Prone |
| Deafened | Invisible | Restrained |
| Exhaustion | Paralyzed | Stunned |
| Frightened | Petrified | Unconscious |
A condition doesn't stack with itself; a recipient either has a condition or doesn't. The Exhaustion condition is an exception to that rule.
