Vassal Harpoon

The Vassal Harpoon is one of eight Vassal Weapons from Glass' World. The current wielder is Sadeena.

Overview
This weapon was originally in the hands of the enemy of the heroes in Glass' World. Eventually, this enemy attacked the heroes and Sadeena primarily faced off against him. Despite his superior power, the Harpoon Reincarnator was not proficient with his weapon so Sadeena easily overwhelmed him. The enemy weapon wielder had thought that the accessory which forced the weapon under his control was a new, unbreakable version but Rino had switched it out. As a result, Sadeena broke the accessory and it chose her as its new worthy wielder.

Power-up Method
The power-up method for the Vassal Harpoon is Skill and Magic Mastery. The more a skill or magic spell is used, it is slowly upgraded.
