My Idea for Diona internal healing is as follows, Say you have broken both of your legs as Diona (Insert name here) and currently can't stand? With this you would have the option to sacrifice about twenty ticks of in game time in which, you would be unconscious and vulnerable while your body mends the broken bones in your legs, I'm suggesting a feature like this to let you heal your broken bones and organs. Because Diona according to lore are a self sufficient race, they don't need food, water, air or atmosphere and they can heal from all the other wounds, But breaking enough bones ingame currently screws you over as your left unable to do anything at all, Forever collapsing and dropping things until a doctor can fix you, With this you have the option to sacrifice your time to heal yourself while being oh so vulnurable because it would take twenty ticks per broken bone and organ for balance reasons
Some feedback on this would be lovely this is only a rough idea
