That may be the difference then. In all the battles Selenia has fought in during this war (protip: a LOT) scrolls have never once been used. The only magical event that happened previously was some kind of portal event where the whole population of Isadril up and abandoned Xavax then raged through Vix and Perdan.
In fact, the only scrolls that I'm aware have been used at all were when Stegman Hemmings targeted her with pain magic 2 or 3 times, then when she used a Fountain of Youth scroll on herself. Lastly, of course, this resurrection. End of list.
