The rules say no Totem burn cards.

Does this mean burn cards from regular supply lines are allowed? How can you tell the difference between them in-game?

Supply Line burn cards, which can be obtained by anyone with supply points relatively easily, are allowed for coop. Totem burn cards are banned in coop because they require DLC to be able to obtain them whereas in Training Mode for solo play, all burn cards are accessible and infinite for everyone. The difference between the two would be the significance of the ability granted by the card. With the supply line cards you get things such as Windfall, Dusty's cards (random shotty or smg, etc), Group Hug, etc. With the Totem Burn cards, you have very significant cards such as Secondary Weapon Upgrade, Primary Weapon Upgrade, Offensive Upgrade, Random Legendary Attachment, Random Legendary Weapon, Squad Armor, Hired Gun. I can understand that it's kind of a pain learning to differentiate between the two in-game but after a discussion amongst runners in the discord, we concluded this would be the best ruling to keep the coop playing field as level and competitive as possible. Hope I could kind of clear things up a bit and if you have anymore ?'s feel free to ask <3

Totem burn cards aren't dlc exclusive

Yes they are. Totems got introduced in DLC 1 - Tunnels of Terror. If you don't have the DLCs there is no way to get Totems, therefor you can't get any totem burn cards.

• You can quick play into games and there is a chance you'll find Hives.
• Duffle bags can give out totem burn cards once you unlock all cosmetics.
• Trials of the worm allows anyone to directly access Hives as long as it's in the map rotation.
