Hey. I've been recently playing a lot of Book of Hours. While casually glitching around, I discovered a mechanics loophole that lets you operate workstations with one mandatory slot empty. There's more information on that here:

Just out of curiosity, I tried this out in Cultist Simulator, and it works there too. Now, it's been years since I last played Cultist Simulator and I'm nowhere near as familiar with its mechanics, but you could probably do some pretty interesting stuff with this in speedruns. One early game example as Aspirant is that you can use Menial Employment over and over again without losing the card, gaining 2 Cash and 1 Health every 10 seconds or so. (Pretty awesome job!)

You can also read a single book repeatedly to gain more and more lore scrap from it. I'm sure there are many other strange interactions too, but testing is still under way.

To do it, click and hold onto a card with left mouse-button, then send the card to nearest verb with right mouse-button, then quickly manually place the card on the verb yourself by moving the mouse and letting go of left mouse-button. This causes the card to first fly into the verb and then return back to its spot (or somewhere nearby) in a boomerang-like fashion. While the card is inside the verb for just a brief moment, the verb can be activated even as the card is already leaving it.

Feel free to give this a try!

EDIT:

Observations on some basic interactions:

• You can use many actions that would normally expend health/reason/passion without expending it.

• you can read books repeatedly to gain their rewards repeatedly.

• you can auction nothing at Oriflamme's and get money for it.

• you can do at least some ritual-type things without expending one of the resources. For instance, in my tests I could reach Grail 7 to promote a follower multiple times in a row with just a basic 2 Grail lore and Silver Spintria.

• you can repeatedly read Bright Young Thing's "Ciphered Diary" to gain 1 Reason and 1 A Red Secret each time.

• buying from Morlands' without cash isn't possible. (You lose 1 cash anyway.)

• recruiting a new person to your cult with no one in the person slot doesn't do anything. (No one gets recruited.)

Still a lot to test.
