For this trophy you have to send a destroyer on a Vendetta Mission. First off find a Orc who has Destroyer under his name and make him your follower. Next get killed by any orcs in the game. Once he's killed you he will be promoted and a Vendetta Mission will appear. Command your new Follower to attack the orc who killed you and your Trophy will pop. Here is my video guide if you have any troubles! Happy Hunting :)
