Medal of Honor: Molduga
The Medal of Honor: Molduga is a key item found in Breath of the Wild. It can be obtained from Kilton after defeating all four Molduga found in the Gerudo Desert. It currently has no use other than bragging rights.
"A medal presented by Kilton in somber honor of having defeated every Molduga. Slaying a monster is a heavy burden to bear. You must steel yourself to carry that weight."
