Here's how you can find them:
1. Enter the Forbidden Forest: This area is unlocked later in the game, so make sure you progress through the story.
2. Look for the Shrivelfig plants: They are located in specific areas of the forest, usually around the edges of the paths or near the trees.
3. Collect them: When you spot a Shrivelfig, simply walk up to it and interact with it to collect it.
Tip: You can use your Revelio spell to highlight the Shrivelfigs in the Forbidden Forest, making them easier to find.
Remember, these plants are used in the game to brew potions and enhance your magical abilities. So, be sure to collect them whenever you see them. Good luck finding them!
