How does X% Chance of Finding Magical Items work for a party?
So I'm running Izual on Normal with a friend, who's having trouble getting the Staff of Herding recipe from him. My question is, how does magic find work since each player in a group will get a different set of items when Izual dies? Since my friend needs the plans, should he be the one striking the killing blow? Or can I?
