Complete Guide for Saved Data in Chaos Zero Nightmare

Fellow travelers battling in the Chaos Zero Nightmare, have you ever experienced such a moment of despair? After painstakingly cultivating a perfect characters for hours, equipped with three Divine Epiphany cards and carefully planned duplicates, only to watch the system mercilessly devour your most crucial core cards in the next second, leaving behind a pile of messy common and basic cards?

Thankfully, the developers have finally heard the players' calls and have completely unveiled this once obscure save mechanism!

LDShop has compiled these rules and explains the saved data mechanism in the simplest way, allowing you to bid farewell to the nightmare of "save file crashes" from now on!

Basics

First, the equipment a character carries, the unique cards obtained, and the content from Epiphanies are guaranteed to be carried over. There is no PT restriction.

However, common cards, normal Epiphanies, Divine Epiphanies, card duplicates, and card removals have a chance to be carried over and are subject to PT value restrictions.

Core Rules Summary:

• Tier Determines Cap: Tier 1 is 30PT, each tier increases the cap by 10PT. For example, Codex Tier 10 means a PT cap of 120.

• Difficulty Affects Capacity: A Codex at Difficulty 5 is roughly 80-90PT. The higher the difficulty, the more space available.
• Real-time Display: The current PT value is displayed in the bottom right corner of the game.

Advanced Knowledge Points:

• After activating Chaos Manifestation Mode, the save file capacity increases by an additional +1 level.
• Save files for different characters are completely independent.

Card Removal Cost List:

• First Removal: 0PT
• Second Removal: 10PT
• Third Removal: 30PT
• Fourth Removal: 50PT
• Fifth Removal: 70PT

Note: Removing Starter Cards or Epiphany Cards adds an extra +20PT. However, removals from Talents are not counted.

Card Duplication Cost List:

• First Duplication: 0PT
• Second Duplication: 10PT
• Third Duplication: 30PT
• Fourth Duplication: 50PT
• Fifth Duplication: 70PT

Note: If the duplicated card has a PT value, then the duplicated card also occupies the same PT.

Card Conversion: Converting a Basic Card to a Neutral Card costs a fixed +10PT (Latest fix: Even if you delete it later, this 10PT is NOT refunded!)
Forbidden Cards: 20 PT

Important Reminder: PT is calculated up to the moment the limit is exceeded; subsequent cards will not be recorded!

Practical Calculation

• 3 Divine Epiphany Cards: 3 × 20PT = 60PT
• Duplicate 2 Divine Epiphany Cards: 0PT + 10PT = 10PT
• Remove 2 Basic Cards: 0PT + 10PT + 20PT × 2 = 50PT
• Total PT Value = 60 + 10 + 50 = 120PT → Perfectly matches Difficulty 9 capacity.

Techniques

• Prioritize removing high-cost, useless cards; low-cost utility cards can be kept.
• Duplicating the same number of times costs half the PT compared to removal!
• Use Conversion for starter cards instead of deleting them; the 20PT penalty is too costly.

Based on the above principles, we can see:

• 1. Don't take Monster Cards – 80 points is enough for 4 Divine Epiphany cards!
• 2. Be cautious removing Starter Cards – the 20PT penalty will make you furious.
• 3. Duplication is better than Removal – the same number of actions costs half the PT.
• 4. Calculate before taking Economy Cards – these 20PT might block a key Divine Epiphany.
• 5. Divine Epiphany Common Cards are point black holes – 20 base + 20 Divine Epiphany = 40 points.
• 6. Conversion is a double-edged sword – used well it saves points, used poorly it wastes them.
• 7. Check your PT value in real-time.
• 8. Difficulty determines the upper limit.
• 9. Utilize the Butcher Shop event – turn cards into meat to get free removal chances.
• 10. There's a 'save' for Boss fights – unwanted Epiphanies can be skipped by force-closing the game!

Different Archetype Save File Planning

• Streamlined Build (Suitable for Orlea, Mika, etc.):
  Remove 3 Basic Cards (10PT) + Duplicate 2 times (10PT) = 20PT → Use remaining space for Divine Epiphanies.
• Divine Epiphany Focus Build (Suitable for Haru, etc.):
  Remove 2 Basic Cards (10PT) + 3 Divine Epiphanies (60PT) = 70PT
• Balanced Build (Suitable for Mei Lin, Khalipe, etc.):
  Remove 2 Basic Cards (10PT) + 1 Divine Epiphany (20PT) + Duplicate 3 times (40PT) = 70PT
