Tips and Strategies

Best Items to Bring

Oran Berry ImageOran Berry Reviver Seed ImageReviver Seed Apple ImageApple

You don't need to bring anything special for Grand Sea aside from the usual recovery items like Oran Berries and Reviver Seeds and food items like Apples.

Best Pokemon to Use

Ampharos ImageAmpharos Lanturn ImageLanturn Magnezone ImageMagnezone

The entire dungeon is filled with Water-type Pokemon, so strong Electric-types that know Discharge can make quick work of rooms full of Pokemon.

Pokemon to Watch Out For

Tentacruel ImageTentacruel Seadra ImageSeadra Qwilfish ImageQwilfish

A lot of the Water-type Pokemon in this dungeon have long-range attacks, so try moving in a zig-zag pattern so that you don't line up with them.
