Pokemon Mystery Dungeon DX: How to Get Rare Qualities

Pokemon Mystery Dungeon: Rescue Team DX is a remake of the original Pokemon Mystery Dungeon titles in 2005 offering alternative gameplay compared to the main series. Taking on the role of a human transformed into a Pokemon, players engage in missions to acquire rewards and move the story forward. Sporting enhanced graphics, the 2020 version also includes other features such as mega evolution, auto-save, and re-tuned mechanics.

The original Mystery Dungeon had IQ as a skill system, allowing Pokemon to learn different passive effects that are helpful for missions or evolve if they needed friendship in the main games. As a key part of strengthening the player's starter and team, IQ was the main way to ensure they made it through difficult dungeons or boss fights. Pokemon Mystery Dungeon DX has re-named IQ into Rare Quantities, but earning them involves a simpler way than before.

Getting Rare Qualities

To acquire Rare Qualities for their Pokemon, players will need to get hold of two items: Rainbow Gummis and DX Gummis. These treats can be found in dungeons, bought in shops, or redeemed from Wonder Mail codes. Feeding a Rainbow Gummi to a Pokemon will sometimes grant a Rare Quality and permanently increase one of their stats: HP, Attack, Special Attack, Defense, Special Defense, or Speed. On the other hand, eating a DX Gummi will grant the stat increase and a guaranteed Rare Quality to the lucky Pokemon.
