I’ve got about 4-6 each of horses, armors, and trophies so far. Most have been random drops. Caldeum steed I think is the one I’ve seen the least frequently. Many people in t4 have spectral charger because I think it drops from legion events or something. My favorite armors I have are probably the lamplighters tack and brigandine barding. My most recent trophy was a dark banner which looks like a flag attached to my horse, so that’s kinda cool.
The decaying steed looks dope, I’d love to use that on a necromancer if I get it!
