(So the players are going to an agricultural town, and on the way pass fields of a purple fruit they’ve never seen before)
(After the Wizard makes a medium nature check)
DM: So this is a fruit called a shimmer pear; it’s purple and people enjoy eating it in the winter because it warms them, but you can’t remember one more thing about it.Rogue: it’s probably poisonous, right?
Wizard: Probably. We should just-
Fighter: Screw it. I eat one.
DM: Alright! Make a Con saving throw
(he fails)
DM: Ok so you fall to the ground, unconscious and poisoned.Rogue: Seriously? I told you!
Wizard: Let’s be poisoned together! I eat one too!
DM: Ok then?
(Wizard then proceeds to roll a nat 20 on his saving throw)
DM: (while laughing) So you, Wizard, find the fruit incredibly delicious and eat a few as you watch your friend froth at the mouth on the ground.Wizard: Perfect!
