Sworn Swords do not take wounds while in a Tale but do take debuffs.
It’s important to note that your Sworn Swords can die from debuffs in Tales! If your Sworn Sword gets three of the same overall Battle / Trade / Intrigue debuffs, they will die! For example, if your Sworn Sword get Hot, then Heatstroke, the next debuff of that type will kill them. You need to balance your Sworn Swords so this does not happen, or they’ll be unavailable until you replace them. Killing a Sworn Sword is pretty rare, so we don’t think it will happen often … but it is possible.
