As we know the sword is a diversified weapon in many games as the same with spiral knights, but the one thing the swords can't do is act like a bomb. The idea is that the charge of the sword would plunge it into the ground and release a pulse. the main idea for this post came from the winmillion the sword that can shoot a shot like a gun my thought was why not make the same thing for a bomb sword.

+1 if u like comment for sugestions

edit:

swing style: double slash then spin
type: original shadow
original name 3* :broken blade 4*: shattered sword 5*: cracked long sword

the troika line only has two status effects at the end the idea of this is to have a wide selection of effects off of the broken blade that would have the same effect(calbur like)... also you could add any type of bomb to it ( large explosion, vortex, shard, needle, and so on)... plus lots of very popular medieval games have plunges to them ( legend of Zelda and Fire emblem come to mind)... I also think it would make a cool effect.
