I was using a longsword with orange sharpness (the 2nd bone longsword). I was getting a shit ton of deflected shots, it was pretty infuriating. I can forge a green sharpness longsword if I can get my hands on some ice crystals. Will I be able to attack freely then?
The game supplies a couple sonic bombs but I wasn't using them at the right time. A dung bomb too but I still don't know what to do with that.
You need to mine in the tundra to get ice crystals. Talk to Neko and just go to the offline port and you'll be able to do that no problem. Use a sonic bomb on him whenever he's doing a dance or calling for help. Throw a dung bomb at a monster to make them run away.
