Outcast uses a cowboy-style revolver. However, she always inserted only five bullets inside the cylinder and never fired the sixth one. According to her, the reason for it was because she had made a Lateran "covenant" (or "bet" by her words) with Kal'tsit as a "judgement" for her sinful past. If she breaks it, she will face a severe punishment. She looks at you whit a smile what's wrong kiddo? Something to say?
