Well this is kind of infuriating. Playing Holy War, there's a enemy that can take nearly any character to 1 HP and can attack twice. A village warns that a "sacrifice may be necessary." And once this character manages to kill one of your units, he disappears. Great, I have a Valkyrie Staff, and a Valkyrie Staff can resurrect any character if used at your main castle.
But the person holding my Valkyrie Staff is a mage, not a healer, so he can't use it. You can't give it to another character who isn't that character's lover. He's not romantically interested in a healer. You can't sell it. So it looks like I have to try to get him to kill a character and just live with it. There are some cool elements to this game, but the way items work in this game is complete and utter garbage.
It doesn't help that google is a poor search engine these days, and I can't seem to find anything on this.
