Poison!

The effects of poison are insidious. A poison will often cause damage if touched, ingested, or, worst of all, injected by a poisoned knife, claw, or fang. The amount of damage varies by type. Characters affected by poison need to make a CONSTITUTION Saving Throw to avoid taking damage AND becoming poisoned!

Being Poisoned

The most terrible effect is the poisoned condition. A character who is poisoned becomes so dizzy and nauseous that they have Disadvantage on all ability checks and all attacks. This effect can last for hours or until a character makes a successful saving throw. 

As usual, the amount of damage and the length of the effect will be listed in the text of our adventures, as well as how often a character can retry a saving throw to shake off the effect.
