Borderlands 2 Container Reference

This page is a reference of the containers found in Borderlands 2 (and associated DLC), and the classes/objects used to determine what loot gets generated when opening the container.

Overview

Containers in BL2/TPS have various attachment points defined on the container's 3D model, generally named like Ammo1, Ammo2, Gun1, Gun2, Grenade1, etc. The InteractiveObjectBalanceDefinition object for each container is where the game says what items should get attached where. For instance, the object GD_Balance_Treasure.ChestGrades.ObjectGrade_DahlEpic (the gigantic red Dahl chest) has the following named loot configurations:

• TreasureChest_2guns2Pistols
• TreasureChest_4Pistols1Long
• TreasureChest_Launcher
• TreasureChest_Gear
• TreasureChest_Shields
• TreasureChest_GrenadeMods
• TreasureChest_ClassMods
• TreasureChest_2Guns&Gear
• TreasureChest_Eridium

As you'd expect, each of those options has a weight-based probability associated with it in a Weight block, which gives you the probability that that pool will be chosen. Inside each of those loot definitions, there's an ItemAttachments object which defines an ItemPoolDefinition/WeaponPoolDefinition to pull from, and a named attachment point. For instance, TreasureChest_2guns2Pistols sets a couple items from GD_Itempools.Treasure_ChestPools.Pool_EpicChest_Weapons_LongGuns to get assigned to Gun1 and Gun2, and a couple items from GD_Itempools.Treasure_ChestPools.Pool_EpicChest_Weapons_Pistols to get assigned to Pistol5 and Pistol6. (There's also various definitions going to Ammo1-4 and Grenade1-4.)

As with many Borderlands objects, this loot pool definition can either be done via a DefaultIncludedLootLists property, which passes off the pool decisions to another object, or with a DefaultLoot property defined right there. (They can also do a combination of the two, of course.)

All of the container InteractiveObjectBalanceDefinition objects are only loaded when a level is loaded, so those objects cannot be modified via standard set commands. The ones which use DefaultIncludedLootLists will often point at a loot pool which can be modified via standard set commands, though there are exceptions.

Notes

The probabilities given below should be more-or-less accurate, though I'm still not totally sure about the exact math behind it. All ammo/health/etc has been ignored here -- this list is only focusing on gear. There's a few places where non-gear loot pools get mentioned, simply because they're part of the decision chain, but they're definitely not the focus.

Some of these pools also have non-100% chances to spawn on each of its defined spawn point. So some of these which say "2x GD_Itempools.Treasure_ChestPools.Pool_EpicChest_Weapons_LongGuns" or whatever may not always spawn two of them, depending on how the RNG feels at the time.

Many of the pools here which are meant to provide shields in the "epic" chests actually have an error in the Shields pool which prevents that pool from ever actually being used. The specific error is that they include the item GD_Itempools.BuffDrinkPools.Pool_BuffDrinks_Euphoria, which cannot be spawned in-game.

"Trap" chests which can spawn Loot Midgets or Varkids or the like are technically different containers than the non-trap versions, and are specified directly in the level definitions. If you want to change the possible loot pools for dumpsters, for instance, you'd technically have to do so in all four classes, since they're separate and don't call out to a common pool.

Main Loot Definition Class: GD_Aster_Lootables.Balance.ObjectGrade_DiceChest

Actual Loot Pool: n/a

This one pulls from many various pools, based on the die roll. The most interesting ones are probably:

• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_1_VeryLowRoll_Longs
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_2_LowRoll_Longs
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_2_LowRoll_Pistols
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_3_HighRoll_Longs
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_4_VeryHighRoll_Launchers
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_4_VeryHighRoll_Longs
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_4_VeryHighRoll_Pistols
• GD_Aster_ItemPools.DiceChestPools.Pool_DiceChest_5_LegendaryRoll_Longs

I think that the "VeryHighRoll" pools only trigger on a single 20, and "LegendaryRoll" only triggers on a double-20.
