“After buying a cup of coffee from the local coffee shop, you notice some unknown white concoction floating inside your drink. As you think about it more and more, you start to feel sick."
When consumed, the player rolls 1d4, which determines the effect, which is gonna affect their character.
1 = Character gains the Poisoned condition for the next 1 hour.
2 = Character is not affected by any effect.
3 = Character is affected by the Charmed condition for the next 1 hour.
4 = Character gains 1 level of Exhaustion and takes 1d4 poison damage.
Additionally, if the player wishes to inspect what's floating inside their drink, they must pass a DC 15 perception check.
If passed, the character remembers how bored and dissatisfied the baristas seemed to be with their job and realises it is most likely someone's saliva.
If failed, the character doesn't think much about it and forgets about it.
