I wouldn’t mind seeing a system similar to what we have with mushrooms right now. I.e. you can still forage wild vegetables at 0 Survival, but they might actually have some negative effects such as being poisonous or just giving you stomach cramps or whatever.
That said, for this to work there’d need to be a system where stats can be obscured if you don’t have the right skill (right now you can just eyeball mushrooms and gauge from the nutrition/fun whether it’s poisonous, hallucinogenic, or benign), and I’m not sure if that’s a direction in which people want DDA to be heading in.
EDIT: or yeah, just do a survival check, but I’d kind of prefer to have these properties as a static value rather than a dice-roll when you actually go to consume them. It just seems more consistent to me.
