As i understand it, it's your wings and halo etc. Not exactly sure how it works.
There are two values for each TF. (except for Fallen, that's a special case)
The first value counts the events which put you further down this TF or back.
They are clamped between 0 and 100 and count down each midnight.
For each TF there are several rules when to count up.
"Angelicness" counts up at midnight if you are a virgin, completely pure and no demon. (virginal demon? would be quite a feat!)
"Wolfiness" counts up every time sperm is exchanged with a wolf.
And so on.
The second value "manifestation" signals the actual level of TF.
All TFs have 6 levels (again except Fallen) so 6 means full TF and 0 none.
At each level you get part of the TF features, like fangs, itching back or scalp, ears, halo, wings... until you have everything at 6.
The levels switch at midnight when you are far enough down this path and all conditions are met. (like only one animal TF at once)
The switching points are different for each TF.
Angel and cat switch at 25, 30, 35, 40, 45, 50.
Wolf, demon and cow switch at 5, 10, 15, 20, 25, 30.
So it takes 50 days of perfect purity for an angel, while wolf could be done in week.
I hope that was not too confusing...
