Player Housing decor really can be earned through everything you do in Midnight. That doesn’t stop when it comes to killing mobs! Here is what you can earn for your house from killing rare enemies in Midnight.
Eversong Woods
Killing all of the rare mobs in Eversong Woods earns the 
A Bloody Song achievement. This rewards the 
Silvermoon Energy Focus decor item.
Voidstorm
The Ultimate Predator achievement comes from killing all rare mobs in Voidstorm, and rewards the 
Opened Domanaar Storage Crate.
Harandar
Defeating the rare creatures of Harandar earns the 
Leaf None Behind achievement, and the 
Lightbloom Moss Mound decor item.
Zul’Aman
Tallest Tree in the Forest is earned from defeating the rare foes of Zul’Aman. This achievement also rewards the 
Colossal Amani Stone Visage.
With Player Housing officially launching with Midnight, this is just the tip of the iceberg when it comes to decor collecting in this expansion.
