So I have a question about Devil room spawning. I was playing as The Lost, and on some levels I didn't get a Devil room despite, you know, not having taken any damage. I did have Holy Mantle, but the wiki doesn't say anything about it messing with your Faith/Evil/Sin. Anyone know what's up?

I got to the Mom fight on that run, and got hosed over by not being able to see the spiders due to Curse of Darkness. I should really just stop playing on Vita so I can pump the gamma when that happens. Alternatively, I can also scum using the save sync feature if I want to, I guess.

Unless you have the goat head, devil and angel rooms aren't guaranteed, even if you don't take damage. There's a high probability chance for them to spawn if you take no red heart damage; but it isn't a guarantee. Book of Belial and goat head are the items you want if you're looking for devil and angel rooms.

Also if you pay for something at the devil room, the probability to see a deal on the next level is decreased.

Your chance for a devil room is reduced significantly if you saw one the previous floor, and reduced by a lesser but still fair chunk if you saw one two floors ago.

Finished Solar System finally yesterday, the game seemed determined to throw the most annoying bosses at me for it though - I got Mask of Infamy and Scolex. Annoying as poo poo to deal with using just orbitals, didn't find many bombs either so I couldn't even use that route.

So I started this last night and got a nice, broken roll involving Pyromaniac, turning into Guppy, and getting the Wafer... when I could only get up to Mom.

Then I tried again and picked up the soy milk, and the shots were so pathetic they couldn't kill Globins before they regenerated.

This game doesn't import your save from the original BoI, does it? There you had to unlock the wafer by completing the game several times, but here it's available straight away.

Devil room mechanics: Having the Goat Head, using a Book of Belial, and possibly using a Devil card (not sure) will cause the devil room door to span 100% of the time. Other than that, you have a base 135% chance for it to appear. Taking red heart damage anywhere on the floor reduces it by 99%, taking red heart damage on the boss reduces it by 35%. Killing one or more beggars or shell games will boost it by 25%, owning certain evil items boosts it 15-25% each. If the door spawned on the previous floor, your total percentage is divided by 4, if it appeared two floors ago the percentage is halved. Only the lowest multiplier counts; if the door shows up two floors in a row it's only a 75% reduction, not 87.5%.

Protip: Go to documents/my games/binding of isaac rebirth/options.ini and set "max scale" from 99 down to 3 or 2. That lets you limit how far the game's graphics scale up to like so:



That's with a limit of 2. If you're in a small room the UI doesn't overlap the floor anymore and if you're in a large room you can see much more than you could before. Enjoy!

Play as Isaac and restart until you bomb into the secret room in the first room and hope for one with an item and/or the item room off of the first room with Ipecac, Fetus, Mind, X-Ray Vision, or Pyro.

Those are pretty much your only options for getting secret room items.

Another thing you can do is if you encounter Greed/Super Greed and they drop their items, or you can get an item to appear in the secret room somehow, you can reroll that item. Not guaranteed, but it's how I managed to fill out every one of my secret room items.

Do all these things apply for angel rooms when you have refused a devil deal? Like, what does killing a beggar do for the chance of an angel room appearing?

I think the percentage is the same regardless of what type the bonus room is. I know Goat's Head and the book definitely work the same for both. Also, keep in mind the type of room is generated as soon as you enter the level, your actions inside the level just affect the likelihood of the door spawning.

I have a logitech gamepad (F310) and it constantly drops the items I am carrying and randomly disconnects, I thought people discussed how to fix this somewhere but I hit a bunch of search terms for this thread and didnt see a solution. It is only this game that has the issue I think (I dont play many games with controllers tho). Any ideas?

Please note, this is for WOTL. These numbers are not known to be the same in Rebirth, although it feels like it's about the same.

The "lower chance for repeats" formula is definitely different because I get back-to-back Devil/Angel rooms all the time without any guarantee item.

How do you manage to not find an item that exists in shops, treasure rooms, random gold chests, and random red chests including devil rooms? I mean of all the unlikely items to just not show up for some person because of bizarre random chance, that's the last item for you to find? I just don't understand.

This is not good evidence that it is different. Assuming you aren't taking red heart damage, the WOTL math says you have a 33.75% chance of getting the second half of a back-to-back deal. (higher if you have pentagram or you've bombed a beggar). That's reasonably high, and this chance is applied often: once for every deal you get before womb 1. So you should expect to see back to back deals at some point on many, if not most, of your runs. I know I got them a lot in WOTL.

I finally sat down to unlock The Lost a few days ago. Had zero issues along the way.

Steam said the cheevo unlocked, but The Lost was nowhere to be seen on the character select, and there was no Continue option on the main menu. Tried doing a new Azazel run to see if that would re-unlock it, but instead I gently caress up and die in Sheol before I even reach Satan. Had to start the process all over, but luckily it unlocked for good the second time.

Moral of the story, take screenshots at your own loving risk right now I guess.

Second time I got Golden God in pre WOTL Isaac, the item that eluded me for freaking ever and took me hours after everything else was wiggle worm.

Also I know this was brought up a bit ago, but I can confirm that at least on the most recent version on PC, quitting out a run and starting a new one will clear out your win streak but it may not actually display until you either win or lose your next game.

On a related note, I'm at the point now where I'm winning more than I'm losing (I don't do restarts or anything and most of the time do random) and I still can't manage to get higher than a 4 win streak. :(

E: I'm also pretty sure that beating Mega Satan does now add to your win streak. At least as long as you kill ??? or The Lamb first.

Jesus, I heard he had gotten a new world record earlier today but I had no idea it was this nuts.I think Problems now holds most of the world records in the longer Rebirth runs. I think he also has the 7 characters to the chest run which is about 1:55 or so.

Although, I guess it kind of makes since that the Dark Room runs would be shorter because there are a lot of ways to skip Womb 2 that don't work for Chest runs.

Actually that's because I didn't clear the Dark Room with Lazarus for a long while. That was one of the last things I did. Pandora's Box was one of the first items I ran into on my next run. My actual last item probably would've been Missing No. since that was the one I actually tried to look for. I got really lucky with Greed dropping the Steam Sale in the Chest and rerolled it several times to get Missing No. Then I finished up the Dark Room with Lazarus.
