Feat: Osteo Armaments
If you have bones, you have a weapon. You create a +1 striking weapon in which you are proficient, made of bone and sinew. If this weapon requires ammunition, mundane bone ammunition is created when you reload it. The weapon falls apart and is destroyed after 1 hour, if you aren't holding the weapon at the end of your turn, or if you use this action again, whichever comes first.
At 8th level, you can destroy an adjacent thrall as part of using this action. If you do, the action gains the thrall trait and the weapon also gains a Decaying Rune, or the Greater Decaying Rune if you're 15th level or higher.
At 10th level, the weapon improves to a +2 striking weapon, increasing to a +2 greater striking weapon at 12th level, a +3 greater striking weapon at 16th level, or a +3 major striking weapon at 19th level.
