A spin-off of Borderlands, Little Tina's Fantasy Lands, like the main series, drops a large number of random weapons like a fountain after defeating enemies. These weapons can only be used if the player's level is up to par, and it is common to earn items that can only be used at the next level in a mission. However, it is not uncommon for dropped weapons to be level-leveled beyond the current in-game level cap.
In the Reddit forum sub-edition of Wonderlands, user afrankiewicz 12 found that players can get weapons with a maximum level requirement of 43. However, it is actually impossible for players in the game to reach level 43: the current level limit of the game in Little Tina's Fantasy Land is 40, and most players will complete the main story of the game around level 30. In the reviews, many players also confirmed that they had encountered the same situation.
However, considering that, like Borderlands, the game will be further increased in the future with the DLC and patch release level caps, it is best not to lose these weapons. The first part of the Little Tina's Fantasy Lands season ticket is scheduled for April 22. Currently dropping weapons in the game that exceed the level limit may be just an oversight or bug.
