Carillons/Dug Weapons

Carillons (聖剣 (カリヨン), Kariyon) or Dug Weapons (ダグウェポン) are powerful ancient instruments created by the Ementwiht (Human) race. They were originally used to give the humans an edge against the other races that filled the world in ancient times, but are now used as instruments against the Seventeen Beasts.

Composition
All Carillons are comprised of multiple shining talismans that form together into the shape of a sword. According to Willem Kmetsch, when talismans are connected using magic, it causes a complex reaction that bestows on the blade entirely new and captivating effects. Each of the swords can be broken up into their individual talismans for tuning purposes.

However, if a person does this incorrectly and places the wrong talisman within a group of incompatible talismans, then the complex reaction can go haywire and trigger an explosion, as seen when Willem takes advantage of it to destroy La Chanteuse using Lapidemsibilus. So, only trained Tunists can repair Carillons.
