Defeat Assembly of Iron in order
Enter Ulduar and defeat the Assembly of Iron bosses in this sequence: Molgeim (Medium) first, then Brundir (Small), then Steelbreaker (Large). On normal difficulty, the pet drops from Molgeim and Steelbreaker. On heroic difficulty, it drops from all three bosses.
Maximize drop chance
For the highest success rate, stealth and strike the first boss before engaging the others, then proceed through the kill sequence without hitting the remaining bosses until you defeat each in order.
