Complete Guide to Infinity Mountain for Digimon World Re:Digitize Decode
(JP3DS)
Important Notes/Advices:
(0). This Dungeon will take you more than 6 real hours to complete when fully
guided and avoiding the battles you're able to, be prepared and don't worry,
you can save your data inside if you're out of steam.
Brace yourself before starting and then carry on. This is both a test of
patience and skill that the average Joe wouldn't be able to complete.
(1). When directed with cardinal directions follow the cardinal points guiding
yourself with the map on the touchscreen and not your character's view.
(2). Evolution Items are dropped Randomly by Bosses inside this Dungeon and
they are not a 100% drop, in fact after a certain floor the drop rates become
really low, here's the detailed list of the Bosses that drop Evolution Items
and the ones that don't.
This Bosses drop Evolution Items so always save before approaching:
Rosemon X at floor 008-02 Drops the X-Antibody Item that allows
Rosemon to become Rosemon X (You are allowed to face her only once).
WarGreymon X at floor 020-03 Drops the X-Antibody Item that allows
Wargreymon to become Wargreymon X.
Examon at floor 030-03 Drops any Random X-Antibody Item except
Beelzemon X's (I recommend to reset until you get Omegamon X's Evolution Item,
otherwise you'll only be able to get it via fishing Seadramon X once at floor
067-12.
ChaosDukemon at floor 040-03 Drops the X-Antibody Item that allows
Dukemon to become Dukemon X.
Mugendramon at floor 050-03 Drops the Evolution Item that allows any
Perfect/Ultimate Digimon to evolve into Mugendramon and Unlocks Mugendramon.
Beelzemon X at floor 060-03 Drops the X-Antibody Item that allows
Beelzemon to become Beelzemon X (You have to finish the Demon Lords Story Arc
in order to fight Beelzemon X, if you haven't you'll fight Chaosmon who doesn't
give any Evolution Item).
Magnamon X at floor 070-03 Drops the X-Antibody Item that allows
Magnamon to become Magnamon X.
UlforceVeedramon X at floor 080-03 Drops the X-Antibody Item that allows
UlforceVeedramon to become UlforceVeedramon X.
Chaosdramon at Floor 090-03 Drops the X-Antibody Item that allows
Wargreymon to become Wargreymon X.
Yggdrasil and Chaosmon at floor 100-03 and 60-03 respectively won't drop
Evolution Items no matter how hard you try, save before Yggdrasil anyway; even
with the aid of Alphamon she can one shot you easily.
(3). You can't bring items from outside here, also after finishing the Dungeon
(or exiting by will) the only items you'll be given are Evolution Items
(Dropped by Bosses) and DigiCodes (Floor 100 rewards).
(4). It's recommended that you use the "Time Switch" to slow down time (if
able) before starting this Dungeon, it will save you some really valuable in
game hours.
(5). Don't freak out, time inside this Dungeon doesn't affect your Digimon
Lifespan, it's a separate timer with the only purpose of keeping your Digimon's
needs in check (Feeding/Pooping/Sleeping Time).
(6). You can use a "DigiStorage Digimon inside, time still goes by as if it was
a normal digimon and it will last the exact same time as a normal Digimon in
there, also; even if it's a 'Storage Digimon' it can still learn techniques
inside.
(7). The time you're allowed inside this Dungeon is always the same, it doesn't
matter if your partner is a Gabumon or an Omegamon X, the only way to extend
your time inside is avoiding care mistakes and using the coloured fruits
dropped by the Bosses and sold in later Vending Machines that extend your time
in there by "x" certain hours, downside is: they don't increase your Digimon's
Weight and if it drops to zero you're out of luck.
(8). Any Digimon that gains stats inside will have the increase removed after
going out.
(9). Try to avoid enemies inside to save time and also to avoid exhaustion, if
your Digimon gets exhausted inside it will faint and all your progress will be
lost. Depending on how tough your Digimon is it may handle 10-20 battles per
day, there's a few floors with a big number of unavoidable battles careful.
(X). If a giant enemy bumps your Digimon you're instantly knocked out, lose all
your items and are bumped to the lobby unless you make your Digimon grow by
touching the Size Switches before facing it.
With that out of the way let's begin the Infinity Mountain guide.
001-012F Sector:
001F:
At your first time here go West, after you trigger the event return and
follow the East path.
002F:
The correct way is West, then North.
003F:
Straight forward path, try to avoid the enemy to save time as always.
004F:
This floor is a trap. If it's your first time talk to Greymon and head
back to the city, ignore the fishing spots at all cost (unless it's your third
time here and you're helping Gomamon X) Talk with Seadramon near Jijimon's
House and tell him that you're stuck, wait two in-game days and he will send
you an email.
He will evolve to Seadramon X and help you touch the solution switch at
the end (which is unreachable by any other means), proceed to the next floor
[If this is your second plus time in here ignore all that and head straight to
the next floor].
005F:
Blue pattern floor map, since it's the Dungeon's first you won't fall in
any way, go to the goal while avoiding battles.

load the data if wrong and try again.
007F:
Amidakuji: The middle is the right path.
008F:
Blue pattern floor map, any tile that isn't blue will drop you to the room
below. You actually want to drop twice here, first one at the start to fight
against Rosemon X; second one in the only hole at the norteast to proceed (You
can only face Rosemon X once).
009F:
Defeat the three enemies to proceed.
010F:
Giant enemy to the North, before approaching him go West, make your
Digimon huge with the size switch, return and head North now.
011F:
Red switch will increase your movement speed drastically touch it and go
North to the blue pattern floor map; any non-blue tile will make you drop to
the floor below, if it's your first time here drop down and touch the slow
movement switch, that will activate the gate, go back up and hit the fast
movement switch, proceed within the blue tiles normally. If this is your second
time ignore dropping down and just proceed.
012F:
If this is your first time go East and battle Dukemon X, if you win the
warp will open. Continue normally and fight Dexmon and then Yggdrasil 7D6, this
will be the end of the X-Antibody Arc, you'll unlock Alphamon and get his
Evolution Item, you can also continue the Dungeon.
If this is your second plus time here go West and fight Mugendramon for a
fruit that will extend your timer for 24 hours, continue North.

Amidakuji: Second from the right is correct if you make a wrong turn
you'll fall.
057F:

so, save your data on the enemy's room.
065F:
Defeat the enemies to continue.
066F:
This floor has a quiz on it, continue to the Message Room. The correct
answer is 5: East.
067F:
Go North in 01 to 03. Continue North. First Time: Go East to 07, then go
North to 09, go East to 10 and then South, flick the switch. Return to 06 and
head North for the next floor.
2nd time plus, at 06 head North to the next floor.
(I): If you go to the East at area 10 you'll find a fishing spot. If you
catch Seadramon X he'll befriend you and grant you a request.
068F:
Touch the switch and head North, hug the walls and continue to the next
floor, don't touch the middle or you'll fall.
069F:
First we want to release the warp that's jammed at 01. Go East and defeat
the enemy at area 09 to release the warp.
If it's your first time here you have to return to 01 and head West to the
solution switch. Then carry on.
070F:
Magnamon X's Boss Room.
Wow, you've made it here, congratulations we're oficially halfway done
through this Dungeon. it's 5:58 am as of writting this, I'm out for a nap...
071-080F Sector:
071F:
As stated before we're at the halfway point. Enemies from now on have
really high stats, if your Digimon has under 3000 Attack and Defense you will
suffer past this point but it's manageable. I managed to complete this Dungeon
with a naturally trained Digimon (no chips, Stats 3000, 1900, 850, 950) so
don't overthink it too much.
Head straight North to the Goal, be careful with exhaustion due to
overload of enemies. Hug corners and try to avoid all you're able to.
072F:
o-× Quiz. Randomized, if you don't know the answer save and pick randomly,
load the data if wrong and try again.
073F:
Head North until area 04, go North at the middle warp here and enter area
05, you should be in a room with an enemy and two purple boxes. Go past the
enemy to the North tile and head to the goal.
074F:
Continue until you make it to 05... Step on the tile behind the message
board and carry on.
075F:
Defeat the enemies to continue.
076F:
At 01 touch the size switch to make your partner huge. then head North
afterwards to the goal (Quick advice: In battles involving huge Digimon the
move Charge Attack is your best friend).
077F:
As directed by the Message Board turn right every time you make it to one
of these, you're only allowed to go straight and turn right at these points
otherwise you'll fall (There's a big shortcut near the start though).
078F:
Strange Floor: Drop beyond the colored tiles until you reach the two
Message Boards.
The solution switch is towards the left Message Board.
The goal is on the cracked floor towards the right Message Board.
079F:
Go West at the start and reach 04. If it's your first time here go
Southwest towards 02 to the solution switch, if you've already activated the
switch in a prior run just head Northwest at 04 and head to Floor 80.
080F:
UlforceVeedramon X's Boss Room.
081-090 Sector:
081F:
At 01 head East, at 02 Head North, at 05 head East and then just carry on.
082F:
o-× Quiz. Randomized, if you don't know the answer save and pick randomly,
load the data if wrong and try again.
083F:
Trap Amidakuji: Go through the middle at the first area and then just go
straight to the goal while ignoring the amida branches.
084F:
The Holy Digimon will tell you the right way to go and the Demon Digimon
will tell you the opposite way. If you don't know Japanese just go West then
East, East again, North and finally South.
085F:
Defeat the enemies to continue.
086F:
Go North, West and then North again. Go up the elevator to the quiz area.
At 03 the answer to the quiz is 9:East so head there.
087F:
Loop Trap. You want to go East in 01, South in 05, North in 11, East in 08
and North again at 12 to reach the goal.
088F:
Go straight at 01 or you'll fall.
You're allowed to move "x" number of spaces specified within the Messaging
Booths on a straight line, aim for another Messaging Booth within those spaces
and you'll make it through.
There's a huge shortcut between the third and fourth Messages though (to
the left).
089F:
At 01 head through the door that's in the upper right. Head North until
you reach area 10. Go Southeast at 10 and again at 09, now go South at 07 and
finally push the solution switch at 02.
Second time plus: Head north at area 10 and again North at 11. There's the
goal.
090F:
Chaosdramon's Boss Room (After fighting him you can purchase the Revive
Floppy that brings you back with 3000 HP, also the fruit that extends your
lifespan by 6 hours).
Beginning of the End: 094-095F and 098F are relentless and extense, going
through them the first time is really annoying but we're only one step away.
091F:
After your surprise fall at 02 go through the colored tiles until you drop
again to 02, then head North to the goal.
092F:
First Time: Head North continuously while avoiding the enemies and find
the solution switch. Return to 01 and go West this time. After entering here go
North twice and head for the next floor.
Second Time plus: At 01 go straight for the goal by following the West
path and then North twice.
093F:
Qinglongmon protects the East, so follow suit and go East until you arrive
to the area with the blue tile. Drop there to the big blue diamond of tiles.
Here just go to the west of this Diamond and continue to the goal.
094F:
This floor goes hand and hand with 095F and they are quite the
inconvenience.
The main mechanic of this floor is this one: All enemies here are giant,
if they touch you all your hard work is gone and you have to start from zero.
The size switch to make your Digimon huge and able to fight them is far
away and after you find it you'll have to fight 6 times.
Save your data upon entering the first room and every time you think you
made progress since you don't want to get one-shotted by the enemies.
You'll have to squeeze past those giant enemies without triggering a
battle if you want to make it to the size switch, then head to the goal.
-At 02 the goal is towards the West, but the enemies here are unskipable
so let's head East until we find the size switch.
-Let's squeeze first pass VictoryGreymon.
-At 05 head North and squeeze past Piedmon. Then make it to the size
switch. Now we fight those two while going back to 02.
-At 02 we go West this time and at 12 head West again. This is the room
with the enemies that will give you trouble, especially Titamon.
Defeat them and head to the goal.
095F:
Defeat the enemies to continue but keep in mind that all of them are
really strong.
After dealing with the ones in the first sector and the barrier opens go
to 06 and drop and head to the next floor.
(The total enemy count in this room is 14 and you already fought 6 enemies
before, be really careful with exhaustion).
096F:
Odd Amidakuji floor: The Amida is connected within multiple maps, the
correct pattern is going straight to different doors and in area 03 going to
the one at the far left.
097F:
This room and the 096 are breathers for what you did in 094-095F and
Go North at 01, West at 03 and North at 04 (You really want to ignore that
Titamon) In the Quiz room go East again to the goal.
098F:
This room is really long, the issue with it is how convoluted the path to
take is.
Most of the floor is divided by cracked tiles that will drop you down...
The solution switch is at the Northeast of the map. The warp to the next
floor is at the Northwest of the map.
At room 01 move one tile to the North, then two tiles to the West and
finally continue North until you drop through the cracked floor.
We're at 10 now, strive for 07 and go through the gate at the Southwest
without falling down in here... There should be a RustTyranomon for refference.
Let's now head East and get to 05. Now we go South. At 02 we have to go
through serveral areas until we reach 13, enemies are easily avoidable.
-If this is your second time going through this floor just go through the
warp at the Northwest of 01 straight to the next floor.
-If this is your first time here: Proceed to drop through the cracked
floor near the Northwest of 01. Drop straight in 09 and head to 07. When there
head to the South area which leads back to 01.
Head to the north of 01 without falling then go Southeast at area 12 and
you can finally hit the solution switch.
Now we head back to area 12 and go to the Northeast to exit at area 13. We
head Northwest here back to area 01 and in area 01 we can finally head for the
goal at the Northwest again.
099F:
If you don't know what you're doing this map is a loop hell, thankfully
I'm here.
Head East at 01, at 05 continue going East. Now continue the single paths
at 06, 03, 09 and 07. When you arrive to 04 head East again and go through
multiple single ending paths until you reach 08. Here go North and we're done.
100F:
Yggdrasil's Room.
Alphamon will aid you in this fight, he's really strong but even with his
help you need a lot of focus during this fight. Even if your Digimon is
overtrained Yggdrasil can easily kill Digimons with 5000 in both attack and
Defence easily if you don't pay attention.
At the same time you don't need to have max stats to defeat Yggdrasil, you
can work a few strategies to make it easily with an average Digimon; you just
have to know what you're doing.
Be careful when Yggdrasil uses it's signature attack, even if you block it
it will do around 10000 damage and of course every time you take Yggdrasil's
hits it will lower your MP a ton, which is really annoying.
Yggdrasil does not drop any Evolution Item. If you defeat Yggdrasil once
per playthrough it will let you choose between four Digicodes, these will max
(9999) a certain stat in battle just by being in your bag. You want either
Defense or Attack/Speed in that order.
Final thoughts:
After complete four runs I noticed that finishing Infinity Mountain completely
it's only worth it the first time, after that you have zero incentive to go
past floor 80.
It's quite frustrating that Chaosdramon drops Wargreymon's X Antibody instead
of dropping his own evolution item. Since you already get Wargreymon X at floor
20 this makes it pointless to go all the way to Floor 90 for another one.
With that being noted you can only evolve to Chaosdramon once per playthrough
since you get his evolution item once at Tentomon's Card Shop after completing
the "Between Heavens" challenges after beating the game...
As per the rewards at Floor 100 they're once per playthrough again. Yggdrasil
only lets you pick a Digicode once and doesn't drop any Evolution items.
With this being said you can actually stack Digicodes by saving Clear Data and
starting a New Game Plus in the same or harder difficulty but that takes too
long.
If I ever decide to do Infinity Mountain again I'll most likely go up Floor 80,
defeat UlforceVeedramon X and return to the lobby with the items.
