Different coloured bags/chests?
The quality of the bag determines what tier crafting materials will drop from it. The equipment, as in armor and weapons, that come out of the bag are dependent on the level of the character opening it.
A level 80 character killing a champion in a level 1-15 zone has a chance of receiving either a white quality champion bag, or an exotic quality champion bag. Just the same as there’s a chance of receiving level 1-15 loot, or level 80 loot when farming mobs in said zone.
If you get a white champ bag, you’ll get tier 1 blood, claws, fangs, dust, etc. regardless of character level when opening. If you get an orange champ bag the material will always be tier 5 or tier 6.
The armor/weapon/trinket that drops from the bag will be the level range of the character that opened it. The equipment dropped will always be green or better as long as your character is level 14 and up. You should only be getting blue gear if opening on a character below level 14. Your character must be level 35 or higher to receive a yellow/rare piece of equipment from a champion bag. Level 62 is the starting point for a chance at an exotic piece of equipment.
The one exception to this rule is the occasional “collectible” exotic items, which are unique to champion bags, and have a low chance of dropping in addition to the normal piece of gear. So if you were opening a champion bag on a level 55 character, you would get your one green or yellow item as well as the chance for a special collectible exotic. A single champion bag has a very rare chance to yield 2 exotic items in this case (as long as the character is level 62+).
You can get blue/fine bags by farming low-mid level zones (I don’t know the actual number range off the top of my head), green/masterwork bags farming mid level zones, and yellow/rare bags by farming mid-high level zones. Level 80 champions will always give orange/exotic bags.
The blue, green, and yellow bags will drop tier 2-4 materials respectively. This includes rare materials such as slivers, fragments, and shards (the lower end components of lodestones).
If you like to save your bags and open them in large quantities on characters of a certain level range for specific armor/weapons, it’s definitely an inventory consuming nuisance, because a wide variety of champion bags can easily take up two full storage panes by themselves. Especially when some bags of the same type/name and color still take separate slots because they can be unique to each other depending on what mob type dropped them, despite them appearing to be the same exact bag.
It is rather annoying, but that’s the general nature of inventory management in this game.
