Mago

Mago   ( 마고, Mahgo, "Mago" ) is Koon Eduan's legendary Spear. It is a Compression Weapon, which when decompressed is said to be able to "pierce half the entire Tower".

When decompressed, its rank increases abnormally.

Trivia

 * Although it is likely that Mago does decompress into ridiculous proportions, it is implied that SIU was joking when he said that it would actually pierce half the tower.
