Cyber Sleuth Great Challenge 1
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: You won against Rina. You’re definitely getting stronger! Do you want to test your strength again?
After accepting Great Challenge 1, travel to the DigiLab and speak with Mirei. She’ll send you to the Zaxon Forum so head there by using Connect Jump on the TV in the Detective Agency. When you get there, speak with Magnamon and Rapdimon (Armor) to challenge them to battle! Magnamon is a free-type while Rapidmon (Armor) is a vaccine. Rapidmon (armor) will do down easy enough by using data Digimon against it. As for Magmon, you’ll want to use piercing attacks or Apocalymon’s Darkness Zone skill which does a flat 444 damage to all foes. Once you defeat the duo, the investigation will be completed. Return to the whiteboard in the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Digi-Egg of Miracles, Digi-Egg of Destiny
Cyber Sleuth Great Challenge 2
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: You easily defeated Magnamon… The next one won’t be so easy!
After accepting Great Challenge 2, travel to the DigiLab and speak with Mirei who will send you to the Tokyo Metropolitan Office. Travel there then head inside to find Leopardmon in the lobby. Speak with him to start a battle against the data-typed Digimon so make sure to bring some virus-typed Digimon to deal double damage to him and use dark skills to increase that damage further. He’ll start the battle by increasing his agility and periodically increase his INT as the fight goes on. Most of the damage he’ll dish out comes from light-based skill. Also, make note that he can cast Support End which prevents a Digimon from using support skills like healing the party or providing buffs/debuffs. Once you’ve defeated him, the investigation will be completed. Return to the whiteboard in the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Leopardmon LM Medal x1
Cyber Sleuth Great Challenge 3
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: That was easy for you, too, huh? Just don’t get too cocky… I’m not impressed yet.
After accepting Great Challenge 3, travel to the DigiLab and speak with Mirei who will send you to Kowloon Lv 5. Return to the Detective Agency then Connect Jump into the TV and travel to Kowloon Lv 5. You’ll then need to work your way to the center of Kowloon Lv 5 to reach Kentaurosmon (vaccine) and Craniamon (vaccine). Since both are vaccines, make sure you bring from data-typed Digimon to deal double the damage to them. When you’re ready to fight, interact with them. During the battle, Kentaurosmon will constantly be boosting his speed while hitting you with guard and speed break field. Meanwhile, Craniamon tends to keep hitting you with earth-based skills while occasionally buffing himself. A Digimon like Kuzuhamon could be helpful by removing their buffs and as always make sure to bring a couple of Digimon that have piercing attacks. Once the pair both go down, the investigation will be completed. Return to the whiteboard in the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Medical Spray DX x5
Cyber Sleuth Great Challenge 4
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: You won again! You’re getting really good. The next Digimon are those guys.
After accepting Great Challenge 4, travel to the DigiLab and speak with Mirei who will send you the Roppongi Underground Research Lab. To get there, travel to the Nakano Underpass and work your way through to the end to find the lab where Crusadermon (virus) and Dynasmon (data) are. Speak with them when you are ready to kick things off. At the start of the fight, they will decrease your speed. Crusadermon will buff her atk and int then hit the part with dark skills while Dynasmon continuously attacks the party. Once you bring them both down, the investigation will be completed. Return to the whiteboard in the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Chrome Digizoid x3
Cyber Sleuth Great Challenge 5
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: You made that look like a piece of cake. I don’t have much left to challenge you… How about a trip to Odaiba?
After accepting Great Challenge 5, travel to the DigiLab and speak with Mirei who will send you to Odaiba. Travel there then work your way north to reach the helipad… where Examon (data) is awaiting you! Approach him when you’re ready to kick things off. This fight might be a little tough as Examon really starts to buff himself once things get going and can deal insane amounts of damage. We used Mastemon with her Chaos Degradation skill to deal chunks of damage to his health at a time while using Acceleration Boost and Corona Destroyer on Beelzemon BM. That did enough damage to finish off Examon with our remaining Digimon. After the dragon goes down, the investigation will be completed. Return to the whiteboard in the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Brave Point A x3
Cyber Sleuth Great Challenge 6
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: Perhaps you haven’t fought these guys yet? They are Digivolved and very strong. Have fun!
After accepting Great Challenge 6, travel to the DigiLab and speak with Mirei who will send you to the Demon’s Den! You can get there by using Connect Jump on the TV in the Detective Agency to access EDEN and then selecting the Demon’s Den URL. When you get there, you’ll see your opponents: Jesmon (data) and Gankoomon (data). Speak with them when you’re ready to kick off the battle which will start with Jesmon boosting their defence. Gankoomon will then apply crit up to Jesmom who’s gearing up to use signature move. Our strategy for this fight was to use Acceleration Boost followed by Corona Destroyer on Beelzemon BM to deal massive damage. We also brought along Armageddemon who deals increased damage to Royal Knights. Once the pair goes down, the investigation will be completed. Return to the whiteboard at the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Exciting Meat x3, Best Meat x2, Miracle Meat x1
Cyber Sleuth Great Challenge 7
Difficulty: 5 Stars
Client: Mirei Mikagura
Place: DigiLab
Details: You must be feeling proud of yourself? I still have more challenges for you. Can you win against those guys?
After accepting Great Challenge 7, travel to the DigiLab and speak with Mirei who will send you to the Valhalla Server. You can reach it by using Connect Jump on the TV in the Detive Agecny then select the Valhalla Server URL in EDEN. You’ll then want to make your way to the deepest part of the area to arrive at our next opponents: Alphamon (vaccine), Omnimon (vaccine), and Gallantmon (virus). For this fight, you’ll want to focus on Gallantmon, and then deal with the other two. One thing to note is that as you defeat a Royal Knight, the other two get a huge power-up. So try to defeat Alphamon and Omnimon as close together as possible. We started out with Alphamon Ouryuken, Mastemon, and Apocalymon to take out Gallantmon then swapped in Beelzemon BM, Armaggeddeon, and Craniamon to take out the other two. Once all three of the Royal Knights are down the investigation will be completed. Return to the whiteboard at the Detective Agency to close the case!
Rewards: 100,000 Yen, 300 CSP, Full Revival Spray x3, Multi-Recovery DX x3
