A comprehensive guide to mastering the Save Data Calculator for Chaos Zero Nightmare - optimize your deck builds and understand point calculations.
The Save Data Calculator is a powerful tool designed to help Chaos Zero Nightmare players optimize their deck configurations while staying within the game's Faint Memory limits. Whether you're planning your next build or experimenting with different character setups, this guide will walk you through everything you need to know.
What is the Save Data Calculator?
In Chaos Zero Nightmare, every modification you make to your deck—adding cards, upgrading them with epiphanies, or removing base cards—costs Faint Memory points. Each tier has a specific point cap, and exceeding it means you'll lose your earliest modifications. The Save Data Calculator helps you:
Plan ahead: See exactly how many points your changes will cost
Optimize builds: Find the most efficient way to achieve your desired deck
Avoid mistakes: Prevent accidentally going over your tier's limit
Experiment freely: Test different configurations without consequences
The calculator follows the exact rules from the official game, so you can trust the calculations to match your in-game experience.
Getting Started
Step 1: Choose Your Character
When you first open the calculator, you'll see a "Select Character" button in the sidebar. Click it to open the character selection panel.
Browse characters: Scroll through 23 playable characters with their portraits
Search functionality: Use the search bar to quickly find your character
Auto-load base cards: Once selected, your character's 8 base cards automatically load
Each character has unique base cards that form the foundation of your deck. The calculator displays actual card images to help you visualize your build.
Step 2: Select Your Tier
The tier selector shows your current progression level. Choose from Tier 1 (30 points) to Tier 13 (150 points). Higher tiers allow for more complex deck modifications.
Tier Caps:
Tier 1-5: 30-70 points (early game)
Tier 6-10: 80-120 points (mid game)
Tier 11-13: 130-150 points (late game)
The progress bar at the bottom shows your current point usage against the tier limit. Watch for color changes:
Green: Safe zone (under limit)
Yellow: Approaching limit (80-95%)
Red: Over limit (modifications will be lost)
Core Features Explained
Adding Cards
Click the "Add Card" button to open the card selection modal. You can add four types of cards:
Neutral Cards (20 points)
General-purpose cards
Can receive epiphanies
Most versatile option
Monster Cards (80 points)
Powerful but expensive
Best for late-game builds
Consider tier cap carefully
Forbidden Cards (20 points)
Special cards with unique properties
Cannot be removed or modified
Always saved, even over cap
Economy Cards (20 points)
100% retention rate
Fixed cost (no additional charges)
Good for stable builds
Monster cards cost 80 points upfront—four times more than neutral cards. Only add them when you have plenty of room in your tier cap.
Epiphany System
Each card (except base cards from certain categories) can receive epiphanies that enhance their power. Click the circle icon on any card to cycle through three states:
None (○): No epiphany, no additional cost
Normal (◐): +10 points (Basic2 cards get this free!)
Divine (●): +20 points extra (total +30 for epiphany)
Special Case - Neutral Cards:
Neutral cards with Divine epiphany cost 30 points for the epiphany (not 20), making the total cost 50 points. This is intentional to balance their versatility.
Removing Cards
Cards can be removed in two ways:
Direct Removal: Click the trash icon
First removal: Free (0 points)
Second removal: 10 points
Third removal: 30 points
Fourth removal: 50 points
Fifth+ removal: +20 points each
Base Card Penalty: Removing base cards costs an extra 20 points unless converted first
Pro Tip: Always convert base cards before removing them! Conversion costs 10 points but saves you the 20-point penalty, netting a 10-point savings.
Converting Cards
The "Convert" button transforms any card into a neutral card for 10 points. This is especially useful for:
Avoiding the base card removal penalty
Gaining access to epiphany upgrades on base cards
Making your deck more flexible
Important: Conversion cost is never refunded, even if you remove the card later.
Duplicating Cards
Need multiple copies of a powerful card? Use the duplicate function:
First duplication: Free (0 points)
Second duplication: 10 points
Third duplication: 30 points
And so on (same scaling as removal)
Duplicated cards inherit all properties of the original (epiphany level, conversion status, etc.) and cost the same points.
Advanced Strategies
Optimization Tips
Convert Before Removing Base Cards
Without conversion: 0 (scaling) + 20 (penalty) = 20 pointsWith conversion: 10 (convert) + 0 (scaling) = 10 pointsSavings: 10 points per base card
Use Free Actions First
Your first removal is free
Your first duplication is free
Plan these carefully for maximum value
Divine Epiphany Considerations
Basic2 cards: Divine costs 20 points (normal is free)
Neutral cards: Divine costs 30 points (total 50 with base)
Monster cards: Divine costs 20 points (total 100 with base)
Forbidden Card Strategy
Forbidden cards are always saved, even over cap
Use them as "insurance" for critical cards
Cannot be modified, so plan carefully
Multi-Slot Management
The calculator supports multiple save slots, allowing you to:
Plan different builds for the same character
Compare various configurations
Keep backup plans
Click the "+" button to add a new slot, or switch between existing slots using the dropdown menu. Each slot maintains independent state and calculations.
Reading the Results Panel
The results panel shows you critical information:
Current Points: Your total Faint Memory usage
Points Remaining: How much room you have left
Percentage Used: Visual indicator of cap utilization
Card Breakdown: Number of cards by type
Action Counts: Total removals and duplications
Use this information to make informed decisions about your next modification.
Practical Examples
Example 1: Early Game Setup (Tier 1 - 30 Points)
Starting with 8 base cards (0 points):
Add 1 neutral card → 20 points
Give it normal epiphany → +10 points
Total: 30 points ✅ Perfect fit!
This basic setup gives you one enhanced neutral card while staying exactly at the cap.
Example 2: Mid-Game Optimization (Tier 5 - 70 Points)
Start with 8 base cards (0 points)
Remove 1 base card (free first removal, +20 penalty) → 20 points
Add 2 neutral cards → 40 points
Give both normal epiphany → +20 points
Total: 80 points ❌ Over limit by 10
Solution: Convert the base card before removing:
Convert 1 base card → 10 points
Remove it (free, no penalty) → 0 points
Add 2 neutral cards → 40 points
Give both normal epiphany → +20 points
Total: 70 points ✅ Optimized!
Example 3: Late-Game Build (Tier 10 - 120 Points)
Complex builds with multiple operations:
Remove 2 base cards (convert first) → 20 points (2×10)
Add 1 monster card → 80 points
Add 1 neutral card with divine epiphany → 50 points
Duplicate the neutral card (free) → 0 points
Total: 150 points ❌ Over by 30
Adjust by:
Skip the second base card removal (-10 points)
Change neutral to normal epiphany (-20 points)
New Total: 120 points ✅
Troubleshooting Common Issues
"Why is my total different from the game?"
Verify conversion status: Conversions cost 10 points even if the card is later removed
Check removal order: The scaling cost depends on total removals, not individual cards
Count divine epiphanies: Neutral cards cost 30 for divine, not 20
"The calculator says I'm over limit, now what?"
Remove modifications: Undo your most recent changes
Downgrade epiphanies: Switch from divine to normal (saves 20 points)
Remove duplicates: Each duplicate removal frees up points equal to the original card's cost
"Can I export my build?"
Currently, the calculator saves your progress automatically in your browser. Use the multi-slot feature to maintain multiple builds. Future updates may include export/import functionality.
The calculator uses your browser's local storage to save your work. Your builds are preserved between sessions, but clearing browser data will reset them.
Tips for Different Playstyles
