As of 3.15 this skill no longer existsEdit
After the skill has been activated, the player will automatically look for herbs, and will stop as soon as he finds one. The herbs the player can find with the skill can be either ready to be collected or still be growing. For this reason the skill is most useful during autumn.
As an activity, dont hesitate to pick up herbs when you see it. Even if you dont know what it is, you can try using it for Physician skill later, trial-and-error style. Store it in cellar to extend its freshness. A minor use is that I can eat one pinch of spoiled plant to induce vomit, but not enough to cause nausea, which is a good way to repeat overeats.
