to make things much more convenient I suggest that you level up your character to around 10-15
you can get free companion from 2nd floor of the Guildhouse by talking to Roanna


you can choose whatever but if you are a fan of ヒカル (an iconic artist from Sugar Star) I suggest picking Harpy

If you head east from the beginning town you will find a cave called D'ark Hideway exit which you will find a Goblin companion

*You will need the ability to pick a lock for the boss' room obtaining from a quest in undercity if i remember correctly*
He will request you to free his friend from guard prison which you can just pay 10k
this part I am not sure anymore sorry
----------------------

Head far east and you will find a dungeon called Sarian Entrance/Exit
this is the earliest dungeon that I can find which houses a Devil that's willing to give seed even if you lose.



First you need to enter at the entrance and defeat the boss otherwise it will be a long journey if the chance of *getting that* failed


After defeating the boss the backdoor will unlock
then you can easily teleport back and forth for this Devil's seed from Sarian Exit.

You will need shoot tons of Karma and even I am not so sure about the exact amount
When I was able to transform I was about 300 Karma 200 Depravity


For easy stealing just head to Blacksmith which will always spawn Lvl1 stealable stuff everyday



up to this point If you have the ability to steal from a person just go to the Guildhouse's basement and steal the fk out of the priestess or from anyone that's indoor with no guards

you can also kill people for a huge boost but that person will be gone forever and too much killing will result in being on the hunt 24/7 so I do not suggest doing that

Now all you need to do is creating a Devil baby
you know what to do
if you do everything right there will be red texts and you will transform.
