Digimon Story Time Stranger: How I Beat Mega + Difficulty Easily, and How You Can Do It Too!…

Steam Community guide by Dancing Fetus.

I beat Mega + difficulty!

I've never written a guide before, but I thought I should share my findings in this game with everyone
I beat mega + difficulty quite easily, mostly on auto except for certain bosses. These are the team I used to beat the game.
Now let’s go over them

Most important: Marineangemon

Why marineangemon?
Well because of its inherent skill Ocean Love being an AoE healing that scales of SPI, meaning you can heal above 10k ++ at once, plus it removes injury and disease on everyone.

Why so much healing when your Max HP is 9999 you might ask?
Well because of this personality skill “Great Embrace”. This personality skill will allow you to overheal your HP meaning your max HP is no longer 9999 but 19998 (if your base HP is 9999). Some enemies in Mega + difficulty can hit you for above 10 k damage even with 9999 DEF and 9999 SPI. Therefore, this personality skill will allow you to tank almost any hit.

This is a rare personality skill of the overprotective personality. You can get it quite easily by switching between overprotective personality and other personality in the farm.
Overprotective personality is to increase healing based of Agent’s Rank, so put that in the Marineangemon.
For skills:

• Spell Boost is very good if you’re playing manually on certain bosses.
• X-Revive is just in case (never actually used it)
• X-Aura is for chronomon (when you get dedigivolved and can’t use Ocean Love)
• Mental break is not needed but you can use it to debuff enemies
  Don’t put other skills such as the one that gives guts or attacking skills because it will brick your Auto.
  Stats priority: HP, SPI, SP, Speed, DEF, you can ignore ATK and INT since she won’t be attacking
  Items: Multi wall (very important, you don’t want to get any status abnormalities), Emerald Arbor Data Fragment to increase your healing again.

Other team members: 2 Magic DPS

Why 2 Magic DPS?
Because of the specific rare personality skill of the Sly variety which is Combo Magic.
What is Combo Magic?
Combo Magic allows you to recast your spells again after you cast a spell essentially doubling your damage. Sadly, this personality only works based of chance. But fret not because we will manipulate the chance, turning it into the literal best personality in the game, making physical DPS completely obsolete.
Same with Great Embrace, you can get it by switching between any personality to Sly back and forth until you get it.

Below is a video of how it works:
Now my choice of magic DPS here are Lucemon SM and GraceNovamon. Lucemon SM is mainly used for Divine Atonement which has a high 90 AoE base power + 15% chance to insta kill (really helps during your adventure), plus being a light element which works with Aegiochusmon:Holy (NPC) lightning shower that debuffs light resistance. While GraceNovamon has a base 80 Calydon Arcus AoE, you can certainly use other magic DPS, and this strat will still works. Other skills are for coverage + spell boost (if needed)
Personality: Astute (ignore SPI by 30% in Agent Rank 10 when attacking)
Items:
The Sky God’s Thunderbolt (stat abnormality immunity + 30% crit rate), if you don’t have it, you can use Multi Wall
Hiroko’s hot perm rod (stat debuff immunity) / Stats Wall (stat debuff immunity)
You can choose to use Blue Steel Data Fragment here to increase your damage by 1.5 instead of the stats wall, but it will double your MP cost making you have to stop to regen your MP every few fights.
Other notable mentions:
Chronomon DM: Allows you to debuff enemies very heavily + good damage
Apocalymon: to kill the last boss faster using Darkness-Zone

Interaction between Great Embrace and Combo Magic

Interaction between Great Embrace and Combo Magic
Now when you read the title, you should see where this is going.
One word: ** Integer overflow**
Okay, that’s two words, but you get where I’m going with this. Because your HP is higher than 9999, the probability calculation of Combo Magic which is based on HP just broke, making your chances of triggering Combo Magic becomes 100% so long as your HP is above 9999, so with Great Embrace, you’re essentially doubling the damage of 2 DPS + providing survivability for everyone.
Like in the clip above, spell boost in this case, boosted not one, but both instance of magic cast. Therefore, doubling your damage again. That is why I run spell boost on both Marineangemon and Aegiochusmon:Holy.
COMBO MAGIC IS PATCHED, NO LONGER GIVES YOU 100% CHANCE WHEN RUN WITH GREAT EMBRACE

The Game Plan

The most perfect game plan for this build is to have 9999 speed for MarineAngemon, then have 9998 or a bit less speed for all your other DPS, this will allow MarineAngemon to always goes first, therefore able to put your great embrace in before you start attacking. This rotation will always be the same during the whole fight, making whatever damage the boss is dealing to you gets negated by MarineAngemon's heal next turn.
To achieve this you need to level all your digimon to 99 before training their speed, otherwise when they level up, your speed will increase to 9999. But this is optional, you can do without it and it's almost the same.
For X-Arts, the best choice is the buff all + negate one turn of damage from enemies. This will allow for a burst damage turn in the form of double spell boost + 50% buff to INT from the X-Arts
Turn 1: X-Arts -> Ocean Love (Marine Angemon) -> damage from 2 magic dps, -> Aegiochusmon spell boost one dps, (All the boss damage is negated by the X-Arts keeping your health above 9999)
Turn 2: spell boost your other dps with Marine Angemon -> double damage from both your magic dps
By the way, combo magic also doubles your CP gain from your DPS, making it available in every 2 or 3 turns. It's very OP.

How to farm for these digimons

You need to have 9999 in all important stats for your digimon. Best done before starting the Mega + difficulty.
For marineangemon you need SPI, SPD, HP, SP, DEF, you can ignore INT and ATK.
Best personality Overprotective
For the magic DPS, you need SPI, SPD, HP, SP, DEF, INT, you can ignore ATK
Best personality Astute
For phys DPS (I like to have one or two just in case) you need SPI, SPD, HP, SP, DEF, ATK, ignore INT
Best personality Brave
After you’ve finished your first playthrough before going to your second, I recommend farming first to get your 9999 stats Digimons, you can easily get the stats by force training them by paying 10k yen each time in the farm, feed them foods for bonds and load enhancement for talent.
Notable farm:

1. Omnimon / Ulforceveedramon --> after further testing the most efficient way to farm Omnimon / Ulforceveedramon when you're just starting to farm is to use a single in-training digimon with the lowest stat possible, give it ClavisAngemon's Charm (you can get this by interacting with Clavis Angemon's back during the Junomon's dungeon, I get it when Tsunomon (Titamon) freeze time and told us to press a switch) and give it physical reflect on its attachment skill. This will allow you to kill Omnimon before you even move (if he happens to use heavy strike and/or spam skills on your said in-training digimon).
   
   
2. Olympus XII --> easily done with marineangemon + 2 magic dps, or 1 magic DPS + the Jesmon you get from farming Omnimon. You can just full auto it while watching Netflix, does not need to have very OP stats here, just max out on main stat, 5k defense, and 5k SPI will do, however, the better speed and other stats are, the more efficient you can farm this. Reward: 700k XP and 300k yen per run. I think I’ve farmed this myself more than 40 runs before entering new game + with over 5 million yen. (didn’t buy any DLC and didn’t need to)
   Lastly this is my last boss run in Mega + difficulty as a bonus

Now you can do it too! Good luck!
