* "City dungeon chest", "Alien tech terminal (event)", "Breaker's Reach crate", "Falling rock", "Breaker's Reach rock", "Broken robot (small)", "Broken robot (large)", "Large Breaker's Reach crate": provisional names. The in-game name has not been confirmed, so this site named the source after its internal name in the drop tables.

"Chance" is the chance to get at least one of this item per try (opening one chest, defeating one enemy, one catch). A "guaranteed group" is the group of a chest or boss from which exactly one item always drops; it does not mean this item always drops (the chance of it being picked from that group is shown in small text). Only items that always drop are marked "Guaranteed". Fishing means catches with a fishing rod, separate from enemy and boss drops. Calculated from the game's drop tables (Conf/Loot, 1.3.0.6) the same way the game rolls them.
