Fret not, though. Nothing is lost in this world, only found in different ways. That's how life works, eh? —Artis

Artis the Mantis is the Explorers' Association accountant. He gives Team Snakemouth the Hard Mode Medal and will reward them for defeating certain enemies while it's equipped.

If a boss is not defeated in Hard Mode the first time it is encountered, its reward must instead be bought from the caravan.
