Ok. That's a big point I didn't think about.
Than discard the visual effects.
But u can bind it in as storyparts for the char.
Like the way in pen & papers.
For example u lose an eye (regardless the way u lose it)
After that u lose a bit off ur sight, like a little blind spot on ur right or something like that.
And u have this info in ur character sheet.
Just an idea don't know how complicated it is to implement it in game and if it makes sense for most players that some actions can have permanent consequences for u.
