Basically, the feature of being able to have your limbs cut off and to cut off enemies’ limbs in combat with a sharp weapon.
If you get an arm cut off in combat, obviously you can’t use it, and if you get your hand that’s holding a weapon cut off you’d drop it, and the same goes for if you cut off an enemy’s weapon hand. Maybe it’d regen once combat is over and something like 30 seconds goes by, or maybe if medical items like healing potions are implimented those would help.
Personal twist (optional)
Devs have said gore won’t ever be a part of the game, so for the animation, I’d say the disintegration one used when something breaks would work.
