Then, once you reach level 4, you've proven yourself a cut above the rest and have probably outgrown that old sheet. You have a decent chance of maybe not dying young, so it's worth it to actually have a full sheet. That's where this second (link to it here) sheet comes in. I figured that, even though I'm adding a lot onto Knave, the majority of characters are still gunna be pretty disposable and won't need a full sheet.
I'll need to playtest these as well but they look promising. And anything on there that you might not yet recognize (the speeds, languages, whatever) are gunna be in the next draft of Brave so don't worry.
