1) Infected Edges: Hole and Cut type wounds, possibly others, will randomly become worse with no event log indication. This could affect how easily you're able to skill with a wound, and possibly cause death if you're afk or not paying attention. I "mined" data from my event logs for the past 2 months and found 3 different versions of this wound condition and about 8 separate infection events. Note this seems to have been around for a while as its mentoned in the gridin everything post.
''Skill Specific Wounds'': Some wounds effectively lower certain skills. For example a wound at the upper or lower back will effectively lower your body strength. You will not see your skill change but your max carrying capacity will decrease. This means that you will get more skill ticks. You want to keep the action difficulty close to 10 pts below you effective skill. See this forum for more details: https://forum.wurmonline.com/index.php?/topic/176149-grindin-everything/
