Entrance from floor 120 in the mines bug

I've never been able to find this staircase described on the lowest level of the mines. Can anyone confirm that this is real? specific instructions and/or a screenshot would be nice.

TownEater (talk) 17:16, 4 March 2016 (EST)

The article is talking about the item staircase that let's you skip a level of the mines without finding the ladder. However that doesn't seem to work for me regardless.

--Haizan (talk) 10:25, 5 March 2016 (EST)

Using the stairs item doesn't work for me either. I have read a bug report stating that using the stairs increases the game's value of the level by one regardlessly of which floor you are on - maning that using it on 120 would lead to floor 121 which is the first floor of Skull Caverns. Maybe this bug is already fixed by now?

--Nocsis (talk) 15:25, 5 March 2016 (EST)

You're no longer allowed to place a staircase at level 120 in the mines. It seems that it was a bug and has been removed: "Removed staircase comment, appears this was a bug and has since been fixed. Can no longer place staircases in mine level 120.", --Lilly (talk) 20:07, 6 January 2017 (UTC)

How far does it go? Or is it infinite?

I bought enough stone stacks to make 100 floors of staircases. When I was done, I reached floor 134. I was really hoping there would be an end, but I did not find anything notable. Thoughts?

I went until floor 201 and it still went deeper, that's when I decided to stop.

A youtuber called DangeriouslyFunny recently used a personal mod to skip 1000 levels at a time and he went over 1 million levels before calling it quits. After I think 10k maybe less you more and more frequently get floors with 100% or near 100% all rocks being iridium ores. Prismatic Shard's drop chance don't seem to change but become more available due purely to shear number of Iridium nodes. At the time of this comment the mod he used isn't publically available, but there is a mod called Skull Cavern Elevators which add elevators like with the mines which updates every 5 levels, should be helpful.

Using CJB's In-Game Cheat Menu mod, I was able to get to, and past floor 144, but on that specific floor three Prismatic Shards dropped from different Iridium Veins, and I was wondering, does this have something to do with the spawn rate of Iridium Veins increasing, or was I just incredibly lucky?

--Teh Matocan (talk) 12:25, 19 March 2016 (PST)

In fact, as I go lower and lower, the occurrence of Prismatic Shards does seem to be increasing.

--Teh Matocan (talk) 12:33, 19 March 2016 (PST)


This is more of an interesting discovery, but I managed to make one of the invincible bugs completely stop by blocking it.

Just an observation. Moox10 (talk) 17:56, 1 April 2016 (EDT)

I was able to do the same, by destroying a rock in front of it right before it was about to turn, this happened multiple times.

the hole

how many floors have you been able to skip using the hole? I just jumped into one and it took me from floor 1 to 4,. but the article mentions its a random amount. How many? Zurgat (talk) 10:14, 10 April 2016 (EDT)

Based on the game's code and it looks like it's random between 3-15 levels, but more than 8 levels is very rare. --Samutz (talk) 12:39, 10 April 2016 (EDT)

v1.3 Treasure Rooms

Spawned according to the following formula, where chance is the chance of finding one:

double chance = 0.01;
chance += Game1.dailyLuck / 10.0 + (double)((float)Game1.player.LuckLevel / 100f);

Daily luck = -0.1 to 0.1; LuckLevel also = -0.1 to 0.1.

By my calculations, on the worst luck day without the special charm, the chance of finding a treasure room for each level is -0.001. On the best luck day with the special charm, the chance is 0.021. --margotbean (talk) 21:49, 30 May 2018 (BST)

HP loss when jumping into shafts

The player can sometimes find a shaft, or hole, which makes it possible to skip 3-15 floors. Jumping down the shaft causes a small amount of damage.

Can we say that this amount of damage is always 3 x #floorsSkiped? At least I have jumped 4, 5, 8 and 9, and the HP lost was 12, 15, 24 and 27 respectively. If we can do it, is it relevant for the article? -- Sapador (talk) 01:45, 22 August 2018 (BST)

Yes, you're right! In MineShaft::enterMineShaft the formula is: = Math.Max(1, - levelsDown * 3);
I'll add it to the page. margotbean (talk) 12:41, 22 August 2018 (BST)
Nice! This also answer a question I had if we could die with these jumps. Thanks :) -- Sapador (talk) 17:27, 22 August 2018 (BST)

Regarding the occurence chance of Iridium Ores and of Ladders or Shafts

I have read on the page that the chance that the chance of finding Iridium Ore is affected by luck and increases significantly every ten floors. No offense to anyone, but...

1. I can't find a source for this claim. I might not have searched enough, and I'm apologizing right now if that's the case, but I think it should have a credible source (ex. a confirmation by ConcernedApe) to verify it.

2. I think it should've been better if there was a calculation of the chance of Iridium Ore appearing in that batch of ten floors. If the chance of occurrence of Iridium Ore is affected by luck and increases only every ten floors, then I think it might go like this:

Iridium ore occurrence chance = Luck + ((Current floor // 10) * Addition every 10 floors)

where // is floor division (or normal division but discard the decimal numbers).

Other than things regarding Iridium Ore, I have seen a comment in the Stardew Valley subreddit ( that includes an expression that shows the percent of a ladder/shaft appearing in a floor. Sorry in advance, but can someone verify this? I know it's not really hard to read a game's code, but I can't understand most of the things there and I might be mistaken with the results that I get.

--KLaurence (talk) 05:01, 30 December 2018 (UTC)

Hello KLaurence -- I agree completely that the statement(s) on the page should provide a reference in the game code, and possibly the exact calculation. I'll put it on my "to do" list! For now, I do believe it's accurate, so we won't remove it from the page entirely.
Also, code reading is never easy -- don't believe anyone who says it is! margotbean (talk) 18:12, 31 December 2018 (UTC)

In the Food section, mention buff "overwrites"

I think it would be worth a small mention in the Food section that buffs don't stack and consuming food that has buffs will replace any existing buffs you have. I've found it's a good idea to carry foods like Fruit Salad or Pink Cake that heal a lot of HP without clearing buffs. This is my first contribution to the wiki so I'd like feedback before making the edit myself. Murgle (talk) 17:07, 14 January 2019 (UTC)

Hi Murgle! Your comment led me to see some inconsistencies in a couple of other pages, so I've corrected those, and then went ahead and added the comment to this page. It's a good point! Thanks! margotbean (talk) 18:19, 14 January 2019 (UTC)
p.s. I forgot to say welcome to the wiki! And next time it will be fine if you make the edit yourself. When I review it, I'll probably say "Hey, that's a good point" and then proceed to change other pages afterwards. Either way.  :D margotbean (talk) 18:30, 14 January 2019 (UTC)
