Mago (마고, Mahgo, "Mago") is Khun 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.[1]
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.
