Dolohov's curse - name/incantation

In the opening paragraph of this entry, HP Wiki gives the name of this curse as "occidere ferio" (meaning, in Latin, something to the effect of "strike to kill"). Where did this come from? As far as I recall this curse was never used verbally nor referred to by its name. 06:59, March 6, 2012 (UTC)


I know I'm the one that approved it (I forget who added it now), but where did the infobox image come from? I thought maybe the Harry Potter for Kinect...? --Hunniebunn (talk) 18:54, October 28, 2012 (UTC)
