Lulab Forest also has Bowl of Assorted Fruit recipe (furniture).

@Al: unless Level-5 decides to add something, I don't think so. I think you just keep getting the fire from drops anyways

Dark Fire keeps dropping from enemies even after all the doors have been opened, do we need the item to craft/buy something else?

Very important thing to note:
In the Depths B1 sealed area, the Shadow Carrotys have a 30% base drop chance for Dark Fire and Slates. The Shadow Carrotella boss has an 80% base drop chance. These are significantly higher than shadow enemies elsewhere, and the same drop rates that of the Treasure Grove.

With at least 240% drop rate gear, these drops are guaranteed. By far the best farming spot for them. You also farm a lot of Crimson Carrots, which are useful for selling in Ginormosia in large numbers.

The Switch version got an update that fixed the opened chests glitch. Turns out the chest in the Lulab Forest area contained a recipe for a decorative fruit bowl!

@DRayX: I've had people report missing recipes that they definitely don't have before so not sure on that one. Some of the recipes seem to be unique to the Sealed Areas as well.

Some recipes can be obtained in more than one location. For example, I've checked shops for the first time and seen that a recipe was already "sold out". I suspect these already open chests are the same thing; you've already obtained the recipe another way. Do you happen to know which recipe it should be? I can check the drop tables to see if it can be found somewhere else.

Turns out the already opened chests might be a bug! Do report it as people are missing recipes because of it. This guide is based off what I personally received from the chests in my game so you can confirm with the recipes I received, but I also had an opened chest in Cave of Trials so I might be missing something from there too

The chest in the Lulab sealed area is empty on Switch too.

@TheUdoon: no idea -- I also had the open chests and thought it was intentional lol!
