Level 15 is the highest level you can reach without risking your soul and level 18 is your target to get rid of the devils. 51 CP does look much, but this can be done with an average of 64 cards. Because the Feast card pops 10 times more than usual, an active player can get this card about 11-12 times per day. See, in about 5 days of mad flipping and Air shuffling this goal can be reached!
As Tyrconnell mentioned over Reddit, the first card of the Intimate story is actually valuable because it provides a Church favour. Free of cost if you don’t have any Devil favours in hand! Over at the Court + Rat, this starting card is around 6.5 EPA or so. Your pick!
Update for 2024: Weasel of Woe can greatly boost your Feast card frequency! This means there are bigger chances to end the story even if you haven’t reached level 15.
This is the chance to get rid of the intimate of devils card forever. You want to keep raising the quality to 18, and you won’t be bothered by the devil’s anymore.
For an option that has a chance of success over 25%, it’s certainly managed to appear only once in a dozen times so far. Still, I’m having fun with these cards. And I’m pleased that this feast, much as Hallowmas, no longer relies on social actions as much as it used to; someone who generally prefers to play alone can get at least some Masquing on their own.
Your pick!
