Where do you get a luminous orb in Pokemon mystery dungeon red rescue team?

You can't get a Luminous Orb in Pokemon Mystery Dungeon: Red Rescue Team. The Luminous Orb is an item introduced in later games, like Pokemon Mystery Dungeon: Explorers of Time, Darkness, and Sky.

In Red Rescue Team, the closest item to the Luminous Orb is the Miracle Seed, which you receive from the Kecleon shop after beating the game. The Miracle Seed helps revive fainted Pokemon, similar to the Luminous Orb's function in later games.
