'Don't over-use an item, you only get so many uses during dungeons. The guns you have will only have a single clip and weapons other than R-type will disappear after many uses, but you will get them back outside of the dungeons.' -Dansei.

'Reaction-type weapons are special and bend the rules because of the way they constantly change. Every monster you kill with it causes it to change a little bit, sometimes even more, so the game thinks it's a new weapon each time. You have another R-type weapon you should be using.' -Dansei.
