Incorrect. I don't remember what the original script was exactly, but it was a Lore check for everyone with a small bonus for rangers and druids, if I remember correctly. But that's the past.
Forage rolls are now a simple d20 roll plus the character's Wisdom modifier. You also gain a +1 to the roll for every 2 levels of ranger, 3 levels of druid, and 4 levels of barbarian. The roll for finding healing herbs is the same, but you only get a +1 bonus for every 3 levels of druid, and 5 levels of ranger. I think the DC is set at 20 right now, but maybe that's a little too high for the majority. I'll lower it a bit for the next update and we'll see how that works.
