On my main, I have nearly full 5* equips now (deadly virulisk helm / coat, and levi blade, as well as wise owlite shield / drake scale shield) and a bunch of other weps / bombs.

Anyways, in all the descents I've made downwards I think I've only ever had 1 item drop? It was in t2 and I found an Autogun. I don't know if a mob dropped it, or if it was somewhere else, so I was hoping for some insight. Where did this come from? How often should items be dropping? I've solo'd in the ballpark of 150-200 t2's / t3's and broken every box and never noticed anything in them... help?
