Rocky Shoreline

Rocky Shoreline, shortened to RS, is a dungeon introduced in PMU 7. It is located in Tanren, West of Tanren Mines.

Scenery
Rain and fog are a common weather status here. The scenery changes once on floor 21, where evolved forms of Pokemon from the lower floors start to appear.

Low Floors (1-20)
The floor is a light sand, and the walls are very dark and rocky. Water is turquoise and comes in an abundance, in large parts and small bits.

Upper Floors (21-40)
The water is now a deeper blue, the floors are grey resembling what could be stone. The walls are still rocky, with bright edges and navy blue centers.

Dungeon Objective
Like most dungeons, the objective is to beat the boss and clear the dungeon. Though, this is a reliable dungeon for Reviver Seed and money farming. It is also the only place Basculin can be obtained.

Tips

 * Reviver Seeds are very common here.
 * Pearls, Big Pearls, Heart Scales, and Honey can be found here. It's recommended to bring a Pokemon with Frisk and a Mobile Scarf or Ghost Pokemon to get the hidden Items that can be found.
 * Bring honey if you're looking to recruit Basculin.
