Kay, so here Is a rundown on this mod snd my experience with it so far and how it plays and how the unlocks work from my understanding.
I'll put numbers to separate the topics.

1.First the Trait, you get this Trait after defeating eye of cthulu, it's on a permanent 2 second countdown that resets, and this should be adjusted because I think It might cause a bug, ill go into detail at the end.

Sinful Trait: the Sinful Trait has a couple of hidden things it does, First, it gives you more hp and ki, for example you will go from 100 hp to 190 and 1000 ki to 3000 [might of been 3500] it also gives you a damage boost to your ki attacks, and it enables you to gain points towards a Sin.

2.Next let's go over the sins,
You use a thought extractor to assign a sin to you, (a quote in the chat log will tell you which along with colored text) as far as I can tell it's RNG and most of the forms are very powerful but you need 150 points in your sin which accumulates slowly over time the thought extractor adds 50 points to the sin it assigns, and the form becomes possible to unlock after you defeat the second boss (often the world evil boss like the brain or worm) at this point you need to let a boss reduce you to below 10% your maximum health then you will get a quote stating that you pleased lucifer and you'll unlock the fork corresponding to your sin, also you can only unlock one of the forms.

3.now let's go over each individual form's stats.

Orange Gluttony "I'm such a pig!"
+200% damage
+100 defense
+100% ki cost
660 ki drain
330 ki drain (Mastered)

Dark Blue Sloth "I just want to laze around and do nothing"
+500% damage
-65% speed
+35 defense
+100% ki cost
660 ki drain per second
330 ki drain per second (Mastered)

Gold Greed "I will be wealthy!"
+350% speed
660 ki drain per second
330 ki drain per second (Mastered)

Purple Pride "I will be better than everyone around me"
+350% damage
+25 defense
+300% ki cost
660 ki drain per second
330 ki drain per second (Mastered)

Green Envy "I am jealous of everyone"
+350% damage
+25 defense
+300% ki cost
660 ki drain per second
330 ki drain per second (Mastered)

Cyan Lust "I'll do anything for pleasure"
+550% damage
+35 defense
+100% ki cost
660 ki drain per second
330 ki drain per second (Mastered)

Red Wrath "I'll get power by any means neccessary"
+750% damage
+100% speed
660 ki drain per second
330 ki drain per second (Mastered)
(For Wrath specifically it doesn't seem like you can get it through the thought extractor so you will need to use the debug item to get it.)

4.Overall thoughts
The mod and the sins are powerful but, there is some clear stand out forms and some clear weaker forms, Greed and Sloth are on the weaker side where as Lust and Wrath clearly stand out, Envy and Pride are basically the same, Gluttony is great for tanking and the overall Trait is really powerful, even if I don't remember the details exactly, it's a clear cut above all the other traits, though getting the forms in the first place are very unintuitive because they give no hints on how it unlocks and use a completely different system from any other dragon ball form across all the mods.

5.Bugs
Now here is the kicker and major bad things about this mod, Wrath, in spite of being among the most powerful form has seemingly no possible legitimate way to obtain it because the thought extractor just won't assign it to you, either that or it's exceptionally rare. And the biggest bug, is whenever I was playing with my friends, using calamity, without fail they would always get disconnected between 20 and 40 minutes of playing after I unlocked the Sinful Trait, and further testing using other traits revealed that only the Sinful Trait would cause crashes and disconnected for the non-host players. I suspect this is because the way the Sinful Trait is implemented has the Trait effectively endlessly refreshing, and potentially causing a data overload, but I can't say anything for sure. If you are using this mod solo, it's amazing snd doesn't have really any major issues, besides the fact that Wrath is impossible to obtain in legitimate ways.
