Wow! Have you upgraded TerrorBlade to a myth? Good!
I have to agree AKITTENINABOWL. And on the second mech, return the second night full and put Damaded Armor Dissolver.
This weapon is not very well balanced. Yes, and different types of damage, a decrease in physical resistance... Hardly any of the developers would approve of this.
It's not a bad idea for a good hybrid mech. But we need to refine it.
