That's cause they're super cool. I wish I had my t-shirt to show you. They gave me one at the Roman camp when we were preparing to fight Commodeman (that's what Leo calls him, but he's not wrong) and Caligula. AGAIN. But I got a lot of healing plants from Pranjal. He's cool. You can use unicorn horn shavings for healing! But not if someone used to be an immortal. Weird.
