wow, this is like whole different game now
i'm new to repentance dlc, just bought it yesterday.
still discovering all the little things that were changed and exploits that got patched out. . .

here are a few.

if you see a devil deal that costs 2 hearts and only have 1 heart, and you try to take it, it pulls from the blue hearts and if you don't have enough , it kills you.

devil bum familiar is further altered to drop hearts even less often, now he drops pills and cards.

d20 now deletes every item in the room on greed mode. .

also bombing the reroll machine in greed mode shop, rerolls the shop twice and then immediately destroys the machine so it can't be rerolled again.

the challenge rooms that you need to have full hp to enter no longer exist. now, all challenge rooms on every floor are now the boss enemy challenge rooms that you need to be at 1/2 heart to enter them and blue hearts now count against that total, there is no getting around this restriction that I know of. . .

devil bums on the floor now pull the damage from you, even if you have I-frames, so you can't get 2 donations in at a time.


I suspect they patched out every little exploit that allows you to break the game.

I suppose these are justified, simce they do feel a bit exploity.


below, these are not really nerfs, but
I noticed many of the "old school" enemies shoot faster, more accurately and from further away.

looks like mom's foot and isaac, blue baby boss, and mega satan have been updated as well, to have more faster attacks and more difficult bullet hell patterns.

I fought the red champion foot and at about 20%, it stopped coming down and wouldn't come down anymore and i had to bait it by walkimg near the doorways so the hand comes out and finish it off that way, which wasn't too fun, since i got hit several times.

Instead of listing off nerfs (though about a third of these are incorrect) try picking up some items you used to think were bad, like Holy Water, Notched Axe, or Crack the Sky. You might be surprised.

That said, Hard Mode was made to be actually hard now rather than just normal mode with less red hearts. Things like the increased enemy fire rate and the chance for smaller shops are Hard Mode exclusives.

oh, its still possible to break the game but they deleted restock machines from the game so you never get any opportunities to choose what shop items you get. there are lots of new ways to break the game too that you can exploit (tainted isaac + nine lives and potato peeler for example)

which ones are incorrect? i'm just stating what I observed. If I made an incorrect assumption based on observations, I would like to be corrected. Educate me.

Good news: There's a card that lets you spawn restock machines.
Bad news: It's pretty uncommon and requires you to beat Greedier mode as Tainted Lazarus, the worst character in the game.

i thought the only change to d20 was that you cant reroll opened chests thus making the duplication process a lot slower

Also, not really a change to D20 itself but batteries are a lot rarer now, meaning its not as easy anymore to break the game with D20.

It's actually still really easy to break greed mode with it, if there's a battery in the shop.

The normal mode gamebreaks with the D20 don't usually rely on random battery pickups. Rather something, like The Habit+Arcades.

You now need to actually pay the deals, yes. But if you don't like the devil path, angel rooms are way WAY better than before. Try them. You can guarantee one spawning if you don't enter to the first devil deal.

The D20 thing I'm not sure, I used it to break Greed and it worked as always.

I think I read somewhere the double reroll when bombing the machines was a bug, but I could be mistaken.

The challenge rooms that need full health exist as always, they're on the 1 part of the chapters, and the one that requires having only one heart is on the 2s. You can bypass the requirement if the secret room spawns adjacent to it, and it always contains an item.

yeah, well I dunno. maybe I still haven't played enough of repentance yet.
but I did 4 runs as lazarus on hard. and 3 runs as bethany , 2 on normal, 1 on hard and on every run, every floor had the red challenge room that you have to have a half a heart to enter. apparently, bethany can't even use blue hearts for health, she uses them for item charges, i guess. but even lazarus, after getting rid of all his red hearts, and having only blue hearts. I couldn't enter any of the red challenge rooms that were on every floor. so I assume they nerfed it so blue hearts count against the entry requirements.
after 3000 hours of play time logged in on this and the OG version combined , I still don't feel confident enough to run around with only 1 hit point remaining as if i'm The Lost without holy mantle, so I guess i'm never going in a red challenge room again . . .


the d20 thing in greed mode. I only tried it once. I was using bethany on normal greed mode. I found the d20. proceeded to clear the first few waves, used the d20, and i was confused when i didn't see a bunch of random stuff appear. I assumed that the coins got pushed away from a bomb blast or something.
but then when all the waves were completed, there seemed to be a lot less coins than before.
I used the d20 again and poof! all the coins just vanished.


as for the reroll machine in the shop. I tried it on 2 separate floors. I used a bomb, and the machine rerolled the shop twice from 1 bomb. I saw the items change twice and then the machine broke on that first bomb. on 2 separate floors, it did the same thing both times.


again, I reiterate, these are observations. this is what happened to me.

Imjust made the assumption that they patched out all the well known tricks and ways that people used exploits to break things in the game, in an effort to make it harder and more like the OG version.

the thing where the 2 heart devil deals kill you if you only have 1 red container that was patched in to the OG version in the final update. even if you had 15 blue hearts and 1 red heart, if you tried to take a 2 heart devil deal, it kills you instantly.
Imassumed they took inspiration from the OG and brought that over here in repentance.


you guys say these are bugs that shouldn't happen, yet they do. is there a way to fix it?



this is not a "complaint thread"
i'm not crying foul like "OMG, THEY SCREWED UP THE GAME, MAKE IT LIKE IT WAS BEFORE!"

it's more of a vent thread, like "wow, gee look how hard the game is now. they even took away all the little exploits I used to use to turn things in my favor and make the game a bit easier to manage".
i'm gonna be at this for a long time, getting all these new unlocks done. .

This is specific to Bethany because Book of Virtues + D20 destroys pickups instead of rerolling them. You can still D20 break Greed Mode as other characters, although it doesn't reroll opened chests anymore.

Do you really like older version of a challenge room, which you could've entered easier, but usually were getting some consumables as from regular room?
It's now gives you boss item room 100% and you can still enter it through secret room, with using some items/cards (even more ways to do it now) and while you don't want to be on 1 red heart, nobody forces you to do it till the end of the floor. Leave some hearts on the ground, clear everything, take forced hits and enter it. Yes, you're most likely gonna fight 2 bosses with like 2 hearts, but that's why its called challenge room.
Also this change really helps if you're already low on health, so many Eden runs were "saved" for me, thanks to guaranteed boss item, even if it's just health up.

The D20 answered above. Book of Virtues have a lot of interesting interactions. Better test something without it next time :)

Double reroll should be a bug, cause it even rerolls twice after donating a lot of coins and blowing by itself. But it was intended to blow up by bombs as most of the other machines, so you forced to use coins more. Not that big of a nerf, right?

Don't understand what you're saying about devil deals. They just made it now, that if you have only 1 red heart container, 2 hearts devil deals cost 1 red heart and 2 soul hearts instead. Even if there's 2 heart devil deal, you shouldn't be able to take it and especially it shouldn't remove all your health and kill you, so idk where you're getting that inspiration from og game.

Maybe there's some mods that can "fix" it, tho almost all of the staff you've listed isn't bugged. Also more updates are coming with fixes, changes etc.

The challenge rooms (red icon on the map) require you have 1 heart tops. If you have also spirit ones, then you have more than one. You can still enter with full health if a secret room spawned next to it, so it's not that bad. Plus some cards or items that open doors.
The other challenge rooms (blue icon on the map) require you have all health containers full (red/coin/probably bone too), doesn't matter if you have blue or black hearts.

I know you're not complaining, I'm just sharing what I know about your points.

If you have more blue/black hearts then heart containers, then the blue challenge room will open anyway, even if your containers are empty.
