GENERAL:
The Collection now stores its special dice and decorative counters in their own bag. Letter Dice, Plague Counters, Hope/Despair Tokens and any additional counters that may be added (That aren't exclusive to a character, such as Remedy's Heal Counters) can be found here. Madness Reigns and the full collection use this pack now; it'll come to Hope vs. Despair in an impending update!

CELESTE: CRYSTAL SOULS:
- Crystal Prison's effect has been revised to better fit within core rules. With it, a new keyword has come—Contraption, which allows a Monster to be both a Monster and an item at the same time.
- Golden Ridge was remade with a proper attackable Room template.

STAND PROUD:
+ New content - one new Stand, 「Sun」, has been added. This Stand requires the use of the Room deck to function; if you aren't playing with it, make sure to remove this Stand first!

MADNESS REIGNS:
- Tweaked the effect of Chaos Lord Escherion and his Staff of Inversion to better reflect original intent and prevent it from sticking around after a Brawl started by his effects ends.
- Buffed Garcello to become an item without using the Companion tag, allowing players to destroy him instead of an item they value if they aren't up to dealing with his debuff. Additionally, the new result can now be modified.
+ New content! Enjoy 11 new Monster cards, 6 new Treasure cards, 4 new Room cards and more, including the first new Curse in a while and some experiments with the new Contraption keyword.

???:
+ Three new Soul Stones based on Madness Reigns characters have been added...

GENERAL
- A foreword has been added to the glossary to help explain some rules differences between the Chaos Collection and the standard Four Souls: Requiem experience.

CELESTE: CRYSTAL SOULS
- All Monsters have been given a new background according to their appearance in the actual games.
- Dash Gem's wording revised to more directly mirror similar official effects (e.g. Lord of the Pit).
- Good Karma and Golden Strawberry had wording revised to account for more Requiem-standard wording.
- H.R.T.'s wording has been revised to be more consistent with the expand's internal logic.
- Mountaineer's Backpack has been revised to use Requiem-standard "max hand size" wording.
- Hyper Dash Gem has been revised to utilize the Requiem-standard "round" wording.
- The Bird has had its effect slightly revised to account for the rare situation where a player has more than three Souls but the game hasn't ended yet (i.e. It Lives!).
- All traces of the original default Event background has been removed from the Events, now being displayed against a stark white background.
- Several Events (Beat Blocks, Celestial Resort Cleanup, In the Mirror) have had their effects rewritten to be easier to understand and more consistent with official language.
- Beat Blocks has been buffed to award 2 Cents per counter and The Cassette Tape at 5 or more counters.

STAND PROUD:
+ New content! Two new Stand items, Stardust Crusaders' 「Justice」 and Diamond is Unbreakable's 「Pearl Jam」 join the mix, plus a new Room—the Devil's Palm from Steel Ball Run will make gaining Stands much easier for all players.
- The rules on Stand items have been adjusted to make them more clear - the "like Eternal items" clause has been changed to simply state that other players can't steal or destroy Stands controlled by another player (Unless otherwise stated). This means that Stands are now valid targets for the death penalty!
- The Hand has been revised to remove its unnecessary "Nothing" roll result, per Requiem standards.

???:
- A certain surprise for Celeste: Crystal Souls fans is now available in a standalone pack...

GENERAL:
- The packaging for the Chaos Collection has been given a huge overhaul, with the different packs now using card-pack models while the Collection as a whole uses a box model.

CELESTE: CRYSTAL SOULS:
- Fixed an issue where The Bird and "A Part of You!" weren't named, despite certain cards instructing the player to find them.

MADNESS REIGNS:
+ The last four Bosses from Furi have arrived, and with them, Madness Reigns' first Development, Feeling FURIous, is now available.
To be clear, all the Furi cards are still part of Madness Reigns proper - there are too few of them to be worthy of their own expansion, but there are enough of them to warrant splitting them off for fans of that specific IP—so this, the "Development," is my compromise. From hereon out, Developments will be placed near, but off of, the board of the expansion from which their cards hail. Additional Developments may be added to Madness Reigns if another IP receives a sufficient amount of representation, and Hope vs. Despair may also be split up into a Development for each game as development on it progresses. For now, I hope Furi fans will be able to enjoy the first Development.
+ Madness Reigns now has a Room deck! Enjoy 13 new Rooms, some based on the various IPs already contained within the expansion, some completely random and made up.

- In accordance with the packaging changes, Madness Reigns' branding and iconography has received a small update.
- Golden Apple of Discord and Thieves' Sack have been updated so that the player who plays them gains resources, then the winner of the Brawl has the opportunity to steal from them. This should incentivize playing them more often, as the player will have immediate access to the resources they're fighting for.
- Updated Curse of Mutiny to use the Curse keyword from Requiem, with a retooled effect accordingly.

CELESTE: CRYSTAL SOULS:
- Madeline has received an experimental buff that lets her activate her character card to add to a roll she made. This is designed to make getting her first counter on Crystal Heart a teeny bit less painful. Feedback on this change would be highly appreciated.
- Badeline's Feather has had its wording updated to be more clear and more in-line with Requiem-style wording.
- Buffed Theo's Instapix! by making the roll use a D4 instead of a D6, making him statistically more likely to hit the shot.

HOPE VS. DESPAIR:
- A few cards have had their name rewritten in a more appropriate font.
- Hope Tokens and Despair Tokens have been re-imported with a more pronounced outline to help them stand out more amongst the chaos.
- Gave "I Agree With That!" a completely new effect to make it similar in power to "No, That's Wrong!"
- Hell Hound Earring's effect was nerfed to, in a roundabout way, protect only one Companion from being discarded.
- Number of instances of Wooden Stick reduced from 3 to 2.
- [DR1 spoilers] The Junko Enoshima Boss has had her effect retooled to allow other players to attack one another, making it easier to interact with her gimmick.
- [DR2 spoilers] The Chiaki Nanami Boss has had its reward increased from 1 Cent to 3 Cents.
+ A little bit more content! Enjoy 4 new Companions based on some of the less important characters from DR1, DR3 and UDG. The DRV3 update is still in the works - thanks for your patience!

MADNESS REIGNS:
- Bomb Imp has had its ability rewritten for clarity.
- An additional clause was added to Tardigrade Shield's ability to clarify its functionality (i.e. that it only works if there's no attack rolls on the stack).
+ Madness grows as yet more esoteric source materials enter the fray. Enjoy a new character, new Treasures and Loot, new Monsters, the whole nine yards!

GENERAL:
- All Monsters with the ability to prevent their own death (Big Bang Monokuma in Hope vs. Despair, Tabi and Culex State 2 in Madness Reigns) have had their ability rewritten to have the attack cancellation/rewards gaining integrated into the text. Accordingly, the "Monster Death Prevention" page of the Glossary has been removed. In its place is a new glossary page detailing terms that have been used for some time but not properly defined (Non-lethal damage, fatal damage, and money Loot cards).

HOPE VS. DESPAIR:
- All character cards have been updated to bear unique backgrounds specific to the Danganronpa series and focus on the characters' upper bodies a little more.
- Kyoko's additional rules card has been rewritten to use more clear and consistent language.
- Chiaki's character card has a new effect to synergize with her starting item but decrease her strength overall.
- Link Bullet has had a note added to it so its phrasing is less ambiguous.
- Robo Justice Suit's ability was rewritten so it no longer makes players completely invincible during Brawls.
- The Monobeasts' Dice have been increased from 3+ to 4+.
- Destroyer Monokuma's effect has had a clause added to clarify intended functionality.
- Kyosuke Munakata's default reward was reduced from 12 Cents to 10 Cents.
- Health for Tanaka's Legion of Darkness has been reduced from 3 to 2.

MADNESS REIGNS:
- Background art for Yoki and Buckets' character cards have been updated to be unique and specific to their respective series. (Since The Drawn is an Isaac character, there are no plans to update his character card art at this time.)
- Audrey Redheart's effect was rewritten for clarity. Additionally, she now bears the [Optional] tag.
+ New content! Enjoy 4 new Bosses and 2 new Events, including a new addition to the line of bosses from Furi and even two cards based on Return of the Obra Dinn.

Small content update today, I'm afraid; more content is in the pipeline, I just need to find the time to test before releasing it.

CRYSTAL SOULS:
- Background art for all character cards except Lani's have been updated to be unique and specific to the Celeste series.
+ Added Rooms! Enjoy 9 new cards, one based on each chapter from the original game.

Hotfix moment!

Fixed an issue where an old version of Murgath's note card explaining Blessings had been erroneously uploaded.

STAND PROUD:
- Fixed an issue where the Stand items had not been added to the expansion standalone bag. Apologies for the inconvenience!

MADNESS REIGNS:

+ New content! Enjoy 2 new unique Loot cards, 4 new Monsters, 7 new Treasures, and a new character - Murgath the Blessed takes up the blade!

- Added an addendum to the Glossary card on Brawls.
- Tithe Box's secondary ability has been tweaked - it now requires a fixed price of 8 Cents, but now guarantees that the player using it will gain a Vow from the bottom of the Monster deck.
- The Impostor has been reworked a little - it now always gives its Loot reward to the player who killed it, and as a counterbalance, it is now External.
- Audrey Redheart's Health increased from 4 to 5.
- Fixed a small language error on Tabi state 1 ("Change" -> "Switch").
- Items in Madness Reigns' Extras Bag are now named! Hope vs. Despair will get similar treatment the next time it's updated, I promise.

CRYSTAL SOULS:
- Fixed an issue where the characters from this pack's Eternal items weren't appearing when pulled from the complete Chaos Collection pack. Sorry!
- The scale on multi-state cards should now be corrected such that they remain the same size when their state is switched.
- Jellyfish has been nerfed such that it loses Dice each time any roll resolves.

STAND PROUD:
- The World has been nerfed to grant only one additional attack to its user so players can stop gaining four Souls in one turn with it. Additionally, the damage it grants upon a kill now only lasts two rolls.
- Echoes has been buffed to remove most aspects of its downside, and its 0 Soul and 1 Soul option have been tweaked accordingly.
