[@Ammokkx] You shouldn't be strict on definition of words because there can be hundreds of definitions of the same word, no to mention your technically fighting me the gm if you really want to keep pushing this issue while breaking rules 1 and 3. I don't rely on the internet for a lot of things for many reasons. I know a would-be-writer who has agreed on my use for Bio many times over. having used Bio as more detailed information about the person/character, which includes stuff like personality, likes, dislikes, and more, while backstory is the history of the character, and when used in correlation to each other like I have there leaves no need to be question. Not being very effective against soft materials isn't really a weakness per say. it's just something their not effective against which many things have things their not effective against, while the sound is something that affects them in negative ways that can undermine them.
