Thaumcraft Treasure Bags

The mod Thaumcraft adds three treasure bags: Common Treasure, Uncommon Treasure, and Rare Treasure. They are obtained primarily by killing Thaumcraft's champion mobs, either by the player or a player-kill device like Diamond Spikes. Right-clicking opens them, which gives a variety of Vanilla and Thaumcraft-related Loot.

Obtaining Treasure Bags

The primary source of treasure bags is by killing champion mobs. Treasure bags are a player-only kill, though some fake players (most notably Dynamism Tablets) can still get them. A treasure bag is guaranteed to drop, and the chances of getting each treasure type are determined by the looting level of the weapon used to kill the mob[1].

Chance of getting each treasure bag
Looting level Common Uncommon Rare
No looting 5/9 4/9 0
Looting I 4/9 5/9 0
Looting II 3/9 5/9 1/9
Looting III 2/9 5/9 2/9
Looting IV 1/9 5/9 3/9
Looting V 0 5/9 4/9
Looting VI 0 4/9 5/9
Looting VII 0 3/9 6/9
Looting VIII 0 2/9 7/9
Looting IX 0 1/9 8/9
Looting X and above 0 0 1

Note that Looting IV and above can only be obtained with non-vanilla methods.

Besides killing champion mobs, Kobolds from The Twilight Forest drop common treasures, and Thaumcraft bosses drop rare treasures.

Loot

When the bag is opened, Thaumcraft generates loot through a multi-step process, and spawns all the items in the player's foot.

Thaumcraft generates between 8 and 12 "loot items" whenever a bag is opened, regardless of its rarity[2]. For common treasure, all loot items are drawn from the weighted loot table below. Uncommon and rare treasures also draw items from the loot table, but uncommon treasures have a 2.5% chance of dropping gear instead, and rare treasures have a 5% chance of dropping gear instead[3]. The gear loot table is described below.

Generating Gear

Uncommon treasures have 2.5% of chance of dropping gear instead of drops from the table above, and rare treasures have 5% of chance of dropping gear[3]. Dropped gear follows a different distribution. The type of gear (either a helmet, chestplate, leggings, boots, or weapon) is chosen with equal probability, and the specific item is chosen with the following weighted distribution.

Weighted probability for each type of gear[7]
Probability[8] Helmet Chestplate Leggings Boots Weapon
25.1% (5012433/20000000) Leather Helmet Leather Tunic Leather Pants Leather Boots Iron Axe
43.8% (35037437/80000000) Golden Helmet Golden Chestplate Golden Leggings Golden Boots Iron Sword
24.1% (3861223/16000000) Chain Helmet Chain Chestplate Chain Leggings Chain Boots Golden Axe
6.15% (492063/8000000) Iron Helmet Iron Chestplate Iron Leggings Iron Boots Golden Sword
0.804% (64307/8000000) Thaumium Helm Thaumium Chestplate Thaumium Leggings Thaumium Boots Thaumium Sword
0.00052% (41933/80000000) Diamond Helmet Diamond Chestplate Diamond Leggings Diamond Boots Diamond Sword
0.0000135% (1083/80000000) Void Helm Void Chestplate Void Leggings Void Boots Void Sword

The gear will be damaged by up to 1/6 of its maximum durability. Gear from uncommon treasure bags have 25% of chance of being enchanted (using a random enchantability between 5 and 18.5), and gear from rare treasure bags have 50% of chance of being enchanted (using a random enchantability between 5 and 32).[8]
