Pokémon Mystery Dungeon: Rescue Team DX Playthrough Part 17 (EXTRA #11 - Kecleon and Shiny Celebi!)
67In this video, I show how to recruit both the hard-hitting Kecleon and the elusive Shiny Celebi!
Kecleon can be recruited like it was in any Mystery Dungeon game prior to this one: you steal from the shop and knock out swarms of Kecleon until one finally decides to join you. I had a MUCH harder time here than in the original, but with a bunch of new friendship modifiers added, I got it really quickly during my most recent attempt! I put the Friendly Rare Quality on Swampert along with the Inviting Orb and a Friend Bow. Using Mega Swampert in the rain is also recommended because of Swift Swim letting you use two consecutive attacks for easy knockouts. You're also able to recruit Kecleon in Joyous Tower, but it's more satisfying doing it this way, in my opinion.
These items are also recommended:
Apples (if you don't have the Tight Belt, it's good to fight off hunger with them)
10+ Reviver Seeds/Tiny Reviver Seeds (you know why)
All Dodge Orb (if you try this with a weaker Pokémon, having high evasiveness is a great thing)
False Swipe TM (not needed, but it increases recruit rate if you knock out a Pokémon with it)
Max Elixirs/Ethers (for if you revive yourself with a Tiny Reviver Seed and run out of PP for moves to use)
Escape Orb (once you've recruited Kecleon and made it to the next floor, you're free to just get out of the dungeon if you're low on resources and don't want to risk losing Kecleon)
Pure Seed (if for whatever reason the Kecleon Shop isn't by a flight of stairs, eat the Pure Seed and warp to the stairs before the Kecleon start coming in)
Shiny Celebi will only appear in a Mystery House after you've completed the Purity Forest. Western Cave (where you fought Mewtwo) has a very high chance of Shiny Celebi being the one inside the Mystery House. No real tips for this one besides taking your time and buying a bunch of Invitations from the Kecleon Shop just in case you're unlucky. You can spend the others trying to hunt for Pokémon you don't have yet!
