Went on a small adventure today with orthaevelve, digitalambler, and digitalambler's boyfriend. We hit a local botanica, which was very well stocked and run by some very nice people. There's a lot of stuff there that I could make use of in my practice, but I didn't have any particular needs at the moment so I was mostly just browsing while orthaevelve and digitalambler were picking out their purchases. Then one of the men there recommended something for me - a Piedra de rayo or stone of lightning. As he'd gone out of his way to find this item and recommend it for me, I decided to buy it. Now that I'm home I'm doing a bit of research and what I've found so far is interesting - they've been known by a lot of names, including "ceraunia", "lightning teeth", "arrows of God", and "fairy darts". Yes, someone in a botanica went out of their way to sell me elfshot.
