Partial Corpsefolk Feat 1

You died from massive traumatic injuries that caused you to lose body parts, or you rotted for a long time before you were brought back as an undead. There is no hiding your undead nature from onlookers unless you are wholly disguised, but you can manipulate your broken shards in creative ways. Your reduced mass gives you a +5-foot status bonus to your land Speed. In addition, you can spend 1 action that has the manipulate trait to break off a jagged piece of your own body to create a commercial knife. You can create a number of knives at a time equal to your Constitution modifier. They can't be sold and don't function for others. Effects that enhance your natural attacks, such as hardlight handwraps, apply their effects to a commercial knife created in this way while you're wielding it.
