I've noticed the game's wiki page for the loot table was outdated. I couldn't figure how to properly edit it there, so I copied it, made my own spreadsheet, and added the new equipments introduced by the Ultimate Edition update. Feel free to use it on Google Drive or download it. It's a lot easier to sort the columns in Excel.

Just like in the wiki, items are tagged by type, level, and rarity, following this scheme:

• Common items, available by default, are represented by the letter C.
  
• Uncommon items, made available by buying Tier I loot upgrades, are marked by the letter U.
  
• Rare items, made available by buying Tier II loot upgrades, are marked by the letter R.
  
• Epic items, made available by buying Tier III loot upgrades, are marked by the letter E.

These are followed by the numbers 1, 2 or 3, representing their levels. An E1 equipment will only appear in the loot pool if you've bought a Tier III loot upgrade and have just killed a level 1 enemy.

• The color green indicates body armors.
  
• The color yellow indicates offhand items.
  
• The color blue indicates headgears.
  
• The color red indicates weapons.

Let me know if you spot any errors!
