Kossetsu [Kodai's staff]

Name: Kossetsu (Japanese for 'broken bone')
Rank: Weak
Type: Bo staff/Sanjiegun (Three-section staff)
Description: A wooden staff 2 meters long. The wood is black-painted red oak. The ends (About fifty centimeters) are capped with black steel. The staff is built so that at a pulse of Kodai's magic, two parts of the staff come apart, forming a three-section staff, connected by metal caps and black steel chains. This allows for greater maneuverability, versatility, and a smaller form for storage. He typically stores it in it's collapsed three-section form in a sheath on his right hip. By channeling his Crash magic through it, he can create spheres of Crash energy at the tips that explode on contact with anything. This can be used to propel Kodai upwards by slamming the staff into the ground. This also gives an extra D-rank hit to the attack.
Strengths:

• Kodai can channel his Crash Magic through it, amplifying it's strikes
  
• Versatile
  
• The transformation into a three-section staff and the sudden change in fighting styles can catch an opponent by surprise
