@IncredibleBee: I have actually explicitly nerfed Dlanor so that her weapon does not work in that way. I did not see Cinder Fall being able to destroy anything and if that is the case then I must have misread. Kiba's abilities were not listed as he has described recently him and that is one of the problems I have with his current playing, Misaka's gun is still capable of being defended against, and Kakine still has limitations that are the only reason I accepted him.
My issues with how you are playing the Dragonslayer are that you seem to believe it instantly destroys any magic at all, and that the explanation you have used to justify this does not make sense. Not that it can harm or deflect magic.
If it really comes down to it, fine, I'll edit what she said or something.
@Earnest Evans: If that's the case I must have missed it, or misunderstood the extent it was meant to fill, and I apologize. However having spoken with people who read Berserk it does not appear that it goes to this level in canon.
Slips of the tongue everywhere. I meant to say Cinder can create anything, but the point still stands.
Anyways, my point is that the Dragonslayer can cut through magic stuff. I have provided several examples of it doing specifically this, including harming one particularly power being made of pure magic. It doesn't just turn magic in the area off, if that's what you're thinking. It will, however, cleave right through it.
Also I'm not sure a simple edit will solve this, if firegirl's personality is any indicator. It's probably best to restart the encounter, but with a different NPC. A polite, less magic-y one.
