Korblox: Berserker's Claymore

Crafted using their corrupted magic, this claymore is as deadly as it is heavy. Handed down from generation to generation to the mightiest Korbloxian warriors, this legendary weapon was once wielded by Canavus himself. With its ability to double its strength in the blink of an eye, this weapon outmatches almost all weapons at close range. Only the mighty knight Xargas is said to have be able to hold his own against this claymore!
