Weapon LoadoutsEdit


  • The MK1-Bo is a weaker version of the standard Bo that deals less overall damage.
  • Its generous status chance makes it useful for slowing down enemies with North Wind or Vicious Frost.


  • The MK1-Bo was introduced as one of three starting Melee weapon options for new players, alongside the Skana and the MK1-Furax.
  • (棒:ぼう) is the Japanese word for stick/rod/staff. Used for various forms and styles of martial arts around the world the staff is a highly versatile weapon. Its composition is usually made of hard wood though its weight could vary from light to heavy, flexible to rigid, and from simple shaft to decorated ornaments. A staff is typically 6 feet long with other staves of various lengths possessing different names.
  • Despite the blue energy depicted in the Bo's portrait, the default energy color of the Bo is red.

Bugs Edit

  • Only the host is capable of ragdolling enemies with the Bo.
  • Executing Slash Dash without holding the MK1-Bo will toggle the channeling effect permanently on your weapon. Sometimes the staff will just continue to shine brightly (while on your back) as if you were channeling it. A melee attack will remove the effect.
