- Defeat an enemy Emperor from any campaign.
Defeat the Emperor of your Home Campaign in the Alliance War.
Emperor Slayer and Emperor Assassin are awarded for landing the killing blow on an Emperor in the Alliance War. It doesn't matter how much damage you do in the fight - only the player who deals the killing blow receives the achievements. The only difference between them is that Emperor Assassin is only awarded for killing the Emperor in your Home Campaign, while Emperor Slayer can be achieved by killing any Emperor. If you kill your Home Campaign's Emperor, you will receive both achievements at once. You'll receive the Armor Dye either way.
