Skull Cavern Treasure room mechanic.

[job application]

So while I was Going on a Iridium Grind run in the skull caverns I stamped upon something very interesting. So I Found 5 treasure Rooms in a row , Like Using The staircase in the Treasure room immediately Made me go to Anthor Treasure room. And If every level has only 1% percent of being A treasure Room , What's the chance of finding 5 in a row. That's an interesting question I wanted to ask because I'm bad at Propalities and I require some help to know the chance. thank you for reading.

I don't know anything about how the mechanic works, but if it's truly random and a flat 1% chance that the floor you enter is a treasure room, then if you're already on a treasure floor, the probability that the next four floors after that are also treasure floors is 1 in 100 million

If you're just on a random skull cavern floor, the probability that the next five are treasure floors is 1 in 10 billion

Luck heavily affects the probability for more rooms, basically every 'point' of luck being another 1% chance to encounter a treasure room on an applicable floor, so the chance is drastically reduced if you were diving with luck buffs/high daily luck (also affects the chance to encounter a treasure room).

Still quite a rare occurrences but much more probable

Damn That's Not Very Common to happen but it did somehow... But I'm searched it and it's For sure the Percentage is 1% or 0.01. anyways @One More Day thanks for reading and helping :)

See, this is the kind of thing I know nothing about and don't check the wiki for when I'm playing

So if I've understood you and the wiki correctly, a +3 Luck buff from a Lucky Lunch on a max luck day would make it 5%, making those chances 625x and 3,125x greater respectively, or 1 in 160,000 and 1 in 3.2 million respectively.

And presumably improved even further if you have the special lucky charm
