@Ziko
well Tsunomon isnt in game
(MetalGarurumon DigiScore dictates that it requires WereGarurumon + Garurumon + Gabumon)
(While WarGreymon requires MEGreymonL + GreymonL + Agumon + Koromon)
Also, if you still dont believe me...
Armaggedonmon requires Diaboromon + Infermon + Chrysalimon + Keramon + Kuramon (DigiFusion and DigiXros Attack)
I'm on Lost Space area where Diaboromon shows up and drops that Armaggedonmon DigiScore... so get your facts straight :> (Still haven't beaten the boss because i'm powering up.)
AND if you want your digimon to become stronger... Grind a few. Collect DigiMelodies, transform them into digimon, leave'm in your Farm (some) and take some of them with you. Focus on 1 Digimon you wanna make stronger.
For example, Greymon at the start, just gave him as many Greymons (after fusing Gabumon + Agumon together) as i can, to learn his Mega Flame EX. (Learns @ L58) Then afterwards i've been just using the Farms to create as many digimons as possible, jogressing them and etc. Shoutmon and the others are crappy until you've given them a few Champions past level 30/Ultimates past level 20 or train a digimon to enable them to gain new attacks.
(I personally recommend Lucemon at level 46. Get his 400MP Skill that buffs ATK and SPD on all digimon in a line in your party by 100%)
That "Greymon" also, is now a Level 94 WarGreymon. Just make sure their levels are RED before you start digifusing/jogressing, to gain maximum aplitutde and stats. He's still L94 since i'm busy translating the game + making guides

Go complete 5 quests. Crystal Volcano should open up. (After you've gotten all 6 Farms)
