Hi All, in my gaming group we are starting a PtG campaign from the ground up, with 600 points order of battle. Is the first time we play narrative after years of matched play. After some games I can say that is a very interesting formats. I have a rule question, if someone could help: My hero was slain in battle, so I need to roll on Injury table, i Roll a 6 = Major Injury. So my Spirit Torment with 5 wound characteristics starts the next battle with 4 wounds (not healable in that game). My question is: what happen next? I don't found any rules to recover (recuperate) this wound, so in the next - next battle my Hero has 4 wound or 5? If it is slain again and I roll again I will have 3 wound? In other words, this Hero Injuries are temporary (just for one game) or permanent throughout the all campaign? I know it can be a silly question, but I don't find any explanation on the rule for Heroes, instead for the Units this aspect is very clearly explained (recuperating rolls and so on). Thank you.
