Hello, hello! Are you looking for the main prize - Gehenna? Although it is quite difficult to get it for free, there is a chance with the combat shackles of BM. You can collect them from MC level 6 and 7. So the idea here is to leave a strong digimon killing instantly digimons giving a level 6 MC.

First, a few recommendations:
1) Have a magnetic card so that you don't have to twitch for all the loot. If you don't have it, just add «4» to the macro to pick up everything.
2) Have a powerful digimon level 95 and above. This way, all your attacks will be critical (if you have a little clone on the crits), and you will instantly kill every digimon.
3) As for the location, I recommend the Coast of the island of files, where Volcamon is located. Go to the upper right corner and leave the bot there, farming.

Now to the important part:
1) If you don't have a digi soul, leave the DS fruit (Digitamamon's Shop) on F5 so that your digi doesn't devolve.
2) If you have enough energy pills, put one on F6 so that you never get tired, and thus you can not complain.
3) I have already created a macro to kill the MC6, feel free to search and use it!
4) I recommend collecting at least 500 MC level 6 to get a lot of rewards. With the money earned from farming monsters, you will also be able to buy a level 6 MC from other players. Do that too.

Anyway, that's all for today! I hope you get lucky and get Hell! Good luck!
