Details
Beyond the Estate
This section contains datamined information about affecting luck. It may contain spoilers for various stages of the game.
Luck is a value that can be changed by luck effects.
- Luck starts each day at 10.
- Spiral of Stars: When "your luck is increased" activates, luck is set to 25.
- Cloister of Rynna: +6 when activated.
- Maid's Chamber: -7 when drafted.
When drafting a room, if the condition is met, additional modifiers are applied for that draft (without modifying the current luck value):
- Veranda: first one in a day gives +12, all later ones give +6. Applied if the room you drafted is green.
- Spare Veranda: +6 per. Applied if the room drafted is green.
- Lucky Rabbit's Foot: +3 if the item is currently in inventory. Also works if you have a Lucky Purse.
Drafting under the Dowsing Rod's effect is luck-adjacent, but it uses its own system which is mostly separate from this one. See its page for details.
Beyond the Estate
This section contains datamined information about luck to item count. It may contain spoilers for various stages of the game.
Most rooms don't use the item count given directly, instead modifying this item count in some way to determine the real item count. See a specific room's page for details on how many items spawn based on luck. Unless otherwise stated, if more items are given from Luck than the amount of remaining items in the room's spawn pool, no additional items spawn, just providing every item in the spawn pool.
Luck Penalty is subtracted from your current Luck value after applying the modifiers that apply to this draft. It increases from the effects below.
- 4- Luck: 7% for 1 item, 93% for 0 items.
- 5-10 Luck: The chance to get 1 item is the first line of the above that applies:
- If Room 46 has been reached, 15%.
- On Day 6 or later, 25%.
- On Day 1, if Veteran Mode was enabled by doing fast early drafts, 23%.
- If Veteran Mode is enabled, 15%.
- On Day 3 or later, 20%.
- Otherwise, 18%.
- If the roll fails, it gives 0 items.
- 11-15 Luck: 1.6% for variable items, 38.4% for 1 item, 60% for 0 items.
- 16-18 Luck: 3.2% for variable items, 76.8% for 1 item, 20% for 0 items.
- 19-22 Luck: Variable items.
- 23-28 Luck: 3 items and +2 to Luck Penalty.
- 29+ Luck: 4 items and +3 to Luck Penalty.
If variable items is chosen, it corresponds to items as follows:

- 17+ Luck: 5% for 3 items and +3 to Luck Penalty; 95% for 2 items and +1 to Luck Penalty.
