Applied it onto my wound and it has given a '15%' of something. What does this indicate? Does it mean that the wound only has a 15% chance of healing? Or that 15% of the wound will be healed? Should I do something more?
the wound will heal, regardless of the shown percentage
the meaning of this percentage is explained in the brodgar wiki page wounds in the section 'treatments' - it's, as I read it, the likelihood of the wound getting worse or combined with other wounds
my assumption was that it was 'heal speed', so a 15% dressed wound would heal at 15% of it's maximum heal speed. I had figured 100% wound heal speed was tailored for PVP and only took a few minutes so you can get back into a siege, or something.
