Floor Item Probability?

Is the chance of getting each item on the floor the same as its rarity via PickUp? Earlier today on round 8 I got 5 Guard Specs in a row, which would obviously be 1/100,000 which seems a bit unlikely. I also didn't get any Hyper Potions after something like round 3.

Well, have you tried via Pick Up?

From a quick look at the disassembly, it looks like the chances are not the standard Pickup chances (as the page currently suggests). It's a bit too complex for me to exhaustively do this now, so I've added a research template instead. Thanks for bringing this up. Nescientist (talk) 22:52, 9 January 2021 (UTC)

I haven't been using a PickUp user on my run I'm afraid - I wasn't explicitly playing for research purposes, just noticed something didn't seem right! WhameWhame (talk) 23:01, 9 January 2021 (UTC)

It appears to depend on both the floor and the round. Apparently, you can get up to 30% chance for Guard Spec., in which case the chance you observe that "only" is about 1 in 400. Nescientist (talk) 23:47, 9 January 2021 (UTC)

I've added the full probability information and presented it in the way I thought was clearest. I'm not that used to reading the disassembly though so apologies if anything is inaccurate. WhameWhame (talk) 12:32, 10 January 2021 (UTC)

Cool, thanks. That's what I had in mind, but thought was too complicated to do now :)

You're apparently faster and/or more diligent reading the disassembly than I am; I hadn't found that Pickup uses constant rates yet. (From my brief look at the disassembly, I didn't believe that tbh.) Nescientist (talk) 12:45, 10 January 2021 (UTC)

As I say, you probably know better than me, but this array seems to give static rates for PickUp probabilities, and is used here. WhameWhame (talk) 12:53, 10 January 2021 (UTC)

Redundand item table

Is there a reason to put an item table from round 1 to round 40? It seems that 21 is equal to 1, 22 to 2 and so on Marcodpat (talk) 21:53, 6 September 2026 (UTC)

I agree, the rows should instead combine all the rounds that have a specific set of items; I would do that myself, but I worry I might mess up the table. Kikugi (talk) 18:38, 7 September 2026 (UTC)

Yeah the only reason I did it like that is because I didn't notice that the items matched - well spotted! WhameWhame (talk) 15:40, 10 September 2026 (UTC)

Per the disassembly, there are separate tables for the Lv. 50 and Open Level challenges, though the two tables have identical contents. In any case, the round number appears to be clamped to 20 rather than repeating. Abcboy (talk) 16:05, 10 September 2026 (UTC)
