How To Complete Cultural Exchange


To complete the Cultural Exchange quest in Monster Hunter Rise, you will have to find 3 Wisplanterns and 3 Boatshells. For the uninformed, Wisplantern — which are considered Account Items —  can only be gathered in the Shrine Ruins and that’s the reason why you don’t have a single Wisplanterns in your inventory.

Boatshells, on the other hand, can be found randomly upon searching through an Oyster Bed on a High-Rank Expedition Tour of the Frost Islands.

How To Complete Economic Stimulation


To complete the Economic Stimulation quest, you will need to find 1 King Rhino, 3 Rock Roses, and 3 Bismuth Prisms.

  • To find King Rhinos in Monster Hunter Rise, you will need to head over to the peak of the Pyramid located in Region 3 of the Flooded Forest. Before heading over to that location, make sure you have crafted Barrel Bomb by combining a fire herb and a small barrel. Use it to open the crumbled door located at the top of the Pyramid.
  • To find Rock Roses, you will need to head over to Sandy Plains on a High-rank Expedition Tour. Once you get to the location, search for a desert rose gathering location. Since these items are randomly found, make sure to keep searching in that location until you get your hands on Rock Roses.
  • To find Bismuth Prisms in MH Rise, you will have to go to the Lava Caverns on a High-Rank Expedition Tour. Similar to Rock Roses, Bismuth Prisms are randomly spawned, make sure to keep searching until you get the required Bismuth Prisms.
