Yup, those are guns strapped to that sword. Apparently the guns fire when the sword is swung. How does that work?

This is the Crowd Controller weapon. This thing causes damage to all enemies in the same space as the target. This is great for cleaning up your opponent’s forces so that your own can push forward. Keep in mind that only Aspects with melee range basic attacks can use it though.

A weird item, but very useful.
