Treasure Grove question

[Ryvaku]

Any reason to explore all floors in it or just rush to the end?

[Lapinoire]

It's just rushing to the end. The only time it matters is if you need Dark Tree Sap, Dark Fish, or Dark Gems, but you can find those behind the Dark Fire Seals around the world.

[PewPew]

Rush unless there's a bonus room somewhere.
