Dhell-Dhell Dhalam

Dhell-Dhell Dhalam ( Zerruzerru Zarāmu, "Kaleidoscope Shadow Formation") is the Extreme Magic of Byoln's Dark Metal Vessel. Byoln uses all of his shadow copies, made from his Dark Metal Vessel powers, to form a shape resembling a kaleidoscope. Byoln and all of his copies attack the enemy at the same time.

Trivia

 * The name of this Extreme Magic is a corruption of the Arabic phrase ظَلام​ ظِلّ الظِلّ Ẓalām Ẓill Al-Ẓill (Ẓ is pronounced as an emphatic "dh" - as in the English word "the", but not as "thin"), which means "Shadow Shadow Darkness".
 * The former spelling "Zetulz Etul" is a misreading of Japanese ゼッルゼッル (Zerruzerru) as ゼツルゼツル (Zetsuruzetsuru).
