With the new danger rooms, and the seeming trend towards optional super hard stuff with higher rewards if you do well, I'd like to propose a new, 3rd, type of treasure box. Essentially, they would operate similarly to the red boxes, in that they would not contain potions (or vitapods?), and with double, maybe increased to triple, as red are already double (i think) heat and crowns. The main difference would be that a tier three box would always contain an item, either a material or a gear drop, and never contain a one star item (so no shards).
