So I was thinking to myself one day after examining the lacerations left on my characters arm after a fight with a bear, "Why not try to add bleeding?"

The prospect is simple, things like animals claws and teeth, bladed weapons like swords and daggers and even arrows have the chance to apply a bleeding debuff, where you slowly lose health over a period of time. The bleeding could be subsided with a bandage item.

Then I wondered, if you can bleed why not bruise? Blunt weapons like maces and war hammers, as well as fists could have a chance to add the 'bruised' debuff, lowering you fatigue a bit and the effect could stack. Axes would have the chance to apply both effects.

My only problem is I have next to no experience with the Creation Kit so I have no idea where I would start.

Would a mod like this be possible in the first place? If so what would be a good place to start?

There's already a mod like this. I can't remember what it's called, but I think maybe Thomas Kaira was the author?
