I decompiled the mod so I could read the code and I still couldn't get it to work. It looks to me like what you're supposed to do is:
1. Have the sinful trait (the trait doesn't show up as a buff like traits in the base mod do, but it'll change the sphere next to your ki bar a dull pink color if you have it)
All the if statements in the mod won't even trigger unless you do.
2. Use the thought extractor
This assigns you one of the seven sins, and you won't gain any progression towards those sins without it. You gain 50 points of progression towards your sin when you do.
3. Wait 10 minutes
You need 150 points of progression in one of the sins. You gain 5 every 1800 ticks, or 10 per minute. You also gain 1 per 1800 ticks towards the other 6.
4. Kill the eater/brain
Only players who have killed "boss2" are considered in the check that actually gives you the forms
5. Drop below 10% health while fighting a boss
You should unlock whichever form(s) you have 150+ points in. It doesn't look like you can trigger this a second time btw, so once you get a form you can't get the others. It seems like you'd be able to get multiple at once, though.

But when I actually tested this I couldn't get it to work. Honestly I just don't think the mod works to begin with, but it's very possible I didn't understand it completely since I don't have very much experience with C# (I do have experience with other languages, mainly Python and Java).

Thank you

Will be testing some possible ideas later but
The sinful trait DOES appear as a buff. You just need to kill EoC for that to happen.
That's how all the traits first work.

Still, this does leave the question of how do we unlock those forms.
I think we may just be missing something. Killing a mechanical boss may be an idea?

Hello all.
Finally managed to unlock the forms with this latest update.
First of all, characters made pre-1.1.0 of this mod won't have the updated code soooo there's that.
As for the forms, I've managed to unlock all but Wrath since I can't get it via thought extractor for some reason.
For clarification, I did all this on a test world with a test character so I had to use hero's mod to spawn some items in.

Here's how I did it:
1) Get the sinful trait and used thought extractor.
2) Killed Eye of Cthullu, Brain of Cthullu, Skeletron, Wall of Flesh, all 3 mechanical bosses.
3) Spawned n equipped solar chest n legs, no helm. Also spawned n equipped endless ki, majin cell, band of regeneration, worm scarf. Spawned and consumed life crystals and vitality crystal. (This step is just so it's easier for me to drop to exactly below 10% HP since that's the requirement)
4) Turned on semi-godmode (the one where you take damage but can't die) and trapped myself in a large box with king slime.
5) waited until I racked up enough points while being hurt by king slime over n over again inside the box to unlock the sin form. (5 of my test characters took about 16m of playtime for this to happen)
6) profit.

According to the mod, killing EoC, Skeletron, WoF, mech bosses shouldn't be required but I just did it to be sure.
Also, it might take several, SEVERAL tries to unlock a form.
Hope this helps.

this is like going to the time chamber to train wtf

i killed the EoC and killed all mechanical bosses but i cant get the sinful trait
