Honey Chests are a type of Chest exclusive to the Hamlet DLC. They have 9 slots and can be found within Mant Hills.
These chests have the unique ability to turn Nectar into Honey after 1/10 of day (48 seconds) of being in the chest. The player does not have to leave the Mant Hill for this transformation to occur.
Upon finding a Honey Chest, it will likely be filled with 9 Honey, one per slot. The player does not have to spread their Nectar out this way, however. For example, placing a stack of 20 Nectar in one slot will produce a stack of 20 Honey in its place. Honey will not spoil while inside the chest.
Honey chests can be hammered, however, they are not craftable and yield nothing.
