Undercroft Dungeon
The entrance to Undercroft Dungeon is located in level 10 of the Wastelands. High combat stats and equipment is recommended. There are lootable chests throughout the dungeon. If you save your Undercroft Key until the last treasure chest at the end (22 keys in a row) you get a chance at the best loot. (AKA don't use your Undercroft Key on the other chests or you'll have to start over.)

Chest Rolls
Each chest appears to have five loot rolls. It's unknown if a higher roll is better or worse, or how the rolls even determine chance based on the odds. Whether a 1.0 roll has a chance to roll anything with a chance less than 1.0, making a lower loot roll more valuable, or if a higher loot roll can generate better loot. It appears to be the latter as higher chests have higher rolls. More Information is needed.
