There is an easy way to make money, but this tactic is an end-game requirement ship...
I'll block some of the text to prevent spoiler-ship for anyone who hasn't played the ENTIRE game...
SPOILERS BELOW!!! VIEW AT YOUR OWN RISK!!!In the Lv. 60
Guardian Tower, on the 14th floor, there's a warp maze where you have to pick one, and hope that it sends you the right way. When you get to the area where the stairs take you to the 5th boss,
Cyborg Octopus, stay in that area and clear out the other enemies within the vicinity (either by killing them, or running away if possible).
Then, have one of your Denpa Men equip an item that gives you Extra Gold X2 (like
Cash Ring+, or the
Rings clothe which is rarely dropped by
Golden Fangs).
Wait around in that area until you see a golden tooth enemy which are known as
Golden Fangs appear out of thin-air... When you see it, run at it as quickly as you can, or it will run off and fade away, making it impossible to battle it.
Once you engage it in combat, two of your Denpa Men need to have a speed of over 400 (estimated) which are able to use Great Rage and Great Haste for all of your party members.
Use certain equips that have the Pierce effect, because the
Golden Fangs have a special move where they can use Guard Shield, which makes them invincible. The Pierce effect can bypass that defence and still land a hit on them.
The
Golden Fangs only have about 640 HP (estimated), so having Denpa Men that have an attack of at least over 340, plus the effect of Great Haste which increase's their speed tenfold, should be about enough to kill them within one turn.
Watch out for their attacks, as they can deal a LOT of damage... unless your Denpa Men is a god with defence, which in that case, you shouldn't worry too much.
Make sure to plan your attacks accordingly... If there are other enemies within the battle against the
Golden Fangs, they might attack the others.
The best way is to have your most damage dealing men take on the
Golden Fangs, while your weak ones can take on the other enemies. This way, you can kill them off quickly before they have a chance to run away in-battle.
Having the Extra Gold X2, killing one of them can net you 20k. Two of them equals to 40k, with three being 60k, and so on...
Make sure not to equip any kind of element bracelet, as their defences are +4 against all types of elements, making your attacks miss (or equal to 0).
Farm these guys for about half an hour and you should gain tons of money quickly.
Hope this answers your question.
