That's the one that jumped out at me almost religiously. I feel like I lost out on something deeply fulfilling and tailored to my very soul.
Edit: It doesn't mention living in a toadstool or a hermit hut covered in them as I had imagined, but I'm sure it's perfectly legal to do that while still upholding your oaths and croaks.
If I had a time machine I would go and be a toad doctor and live in a little cottage in the woods and have a ton of wacky ingredients and stuff everywhere.
