This will help you get all the endings for Her Lie I Tried to Believe Extended Edition.
There might be variations for some but I found these choice combinations to always be on point for their respective endings.
A – when asked to confront Cassandra about the Business Card
B – when asked to hurt Cassandra or restrain yourself
C – when asked to own or disown your fault
One Last Clue
2 2 2 1 1 A|1| B|1| C|1|
Cul-de-sac
1 1 1 2 2 A|1| B|1| C|1|
Illusion of a Beast
*I don’t think anything else matters as long as you choose A|1| B|1| C|2|*
Too Little Too Late
*I don’t think anything else matters as long as you choose A|1| B|2|*
Her Lie I Couldn’t Believe
2 2 2 1 1 A|2|
Note: Readers wouldn’t get the HLICB ending on their very first run of the story since the novel won’t allow A|2| to be chosen even with the right previous choices but it should work after you finish with the OLC ending and replay the whole thing again. (I don’t know if it works with other endings but the OLC one should work just fine)
Have fun 💗
