It would be tempting to say that you get exactly what you deserve for focusing so narrowly on conjuration 9, but I am more interested in how you managed to assassinate four Ermor Wraith Commanders in one round - that is an impressive feat and, considering it was done in your dominion, a fairly heavy blow to your opponents death gem economy as they are gone forever. Well done - now how did you do it?
