Chaos Zero Nightmare Gacha System Guide - Master Banners & Pity

Understanding the Chaos Zero Nightmare gacha system is crucial for building a competitive roster without overspending. This comprehensive guide covers banner mechanics, pull rates, pity systems, and optimal F2P pulling strategies to maximize your character collection.

Whether you're a new player planning your rerolls or a veteran managing limited banner pity, this guide has everything you need to navigate CZN's summoning system efficiently.

How the Gacha System Works

CZN uses a Rescue Banner system where you pull for Combatants (characters). Unlike equipment gachas in other games, CZN only features character summoning, making the gacha more predictable and F2P-friendly.

Summoning Currency

Two currencies power the gacha system:

• Rescue Tickets: Premium currency for single pulls (1 ticket = 1 pull). Earned from events, dailies, and achievements. Use these on Standard Banner.
• Crystals: Main premium currency. 300 crystals = 1 pull, 3,000 crystals = 10-pull (no bonus for 10-pulls). Save for limited banners.

Pull Rates & Probabilities

CZN's gacha rates are transparent and displayed in-game. Here's the breakdown:

What is Soft Pity?

Starting at pull 76, your 5-star rate increases by 0.6% per pull. By pull 85, you have ~8% chance per pull. This significantly improves odds before hitting hard pity at 90.

Example calculation: At pull 80, your rate is 2% + (80-75) × 0.6% = 5% chance to pull a 5-star. Most players hit 5-star between pulls 76-85.

Pity System Explained

CZN's pity system guarantees you won't go unlucky forever. Here's how it works:

Hard Pity (90 Pulls)

If you don't pull a 5-star within 89 pulls, your 90th pull is a guaranteed 5-star. This is the maximum you'll ever need to invest for a 5-star character.

50/50 System (Limited Banners Only)

On Limited Character Banners:

• First 5-star: 50% chance to be the featured limited unit, 50% chance to be an off-banner 5-star
• Second 5-star (if you lost 50/50): 100% guaranteed to be the featured limited unit

Worst-case scenario: Lose 50/50 at pull 90, then need another 90 pulls = 28,800 crystals (180 pulls total) to guarantee a limited character.

Pity Carryover Rules

Pity carries over within the same banner type:

• ✅ Standard Banner → Next Standard Banner
• ✅ Limited Banner A → Limited Banner B
• ❌ Standard Banner → Limited Banner (separate pity counters)
• ❌ Limited Banner → Beginner Banner (separate pity)

Banner Types

1. Standard Banner (Permanent)

Features: All permanent 5-star characters (Khalipe, Mei Lin, Nia, Aria, Lyra, Zane, etc.)

Currency: Rescue Tickets or Crystals

Best for: Rerolling new accounts. Check our Reroll Guide for optimal strategy.

Pros: No limited pressure, all units return

Cons: No rate-up on specific characters (diluted 5-star pool)

2. Limited Character Banner (Rotating)

Features: One exclusive 5-star with rate-up (e.g., Haru, limited-time units)

Currency: Crystals only

Best for: Targeting specific meta characters from our Tier List

Pros: Higher chance for featured unit (50% on-banner, 100% after losing 50/50)

Cons: Limited units rarely return (6-12 month wait for reruns)

3. Beginner Banner (One-time Special Rescue)

Features: Guarantees 1x 5-star within 50 pulls (instead of 90)

Currency: Crystals only

Best for: New players after securing reroll on Standard

Pros: Reduced pity (50 vs 90), one-time discount

Cons: Pool includes all standard 5-stars (no rate-up)

F2P Pulling Strategy

Maximize your roster as a free-to-play player with these strategic guidelines:

Phase 1: Reroll on Standard Banner

1. Create guest account
2. Complete tutorial (~10 minutes)
3. Claim 40+ free pulls from mailbox and missions
4. Pull on Standard Banner until you get Khalipe, Mei Lin, or Nia (S-tier from our best characters list)
5. If no S-tier? Restart and reroll again

Time investment: 2-4 hours on average. See our Reroll Guide for detailed instructions.

Phase 2: Use Beginner Banner

After securing your reroll S-tier:

1. Bind your account (Settings → Link Email)
2. Spend next 50 pulls on Beginner Banner
3. Guaranteed 5-star at pull 50 (likely pull between 30-50 due to soft pity)

This gives you 2x S-tier or A-tier characters within first week—a massive head start.

Phase 3: Save for Limited Banners

Stop pulling on Standard after Beginner Banner. From here:

• Hoard crystals for limited character banners
• Target: 28,800 crystals (180 pulls) to guarantee limited unit
• Only pull if the limited character is meta-changing or a favorite

F2P Crystal Income

Here's how many pulls F2P players earn monthly:

• Daily Missions: 40 crystals/day × 30 = 1,200 crystals (4 pulls)
• Weekly Missions: 300 crystals/week × 4 = 1,200 crystals (4 pulls)
• Events: ~2,400 crystals/month (8 pulls)
• Story/Achievements: ~1,800 crystals/month (6 pulls)
• Maintenance Compensation: ~600 crystals/month (2 pulls)
• Guild Rewards: ~900 crystals/month (3 pulls)

Total: ~8,100 crystals/month = 27 pulls

This means F2P players can hit pity every ~3 months (90 pulls) or guarantee a limited character every ~6-7 months (180 pulls worst-case).

Should You Spend Money?

Best Value Packs

If you decide to spend, prioritize these packs for maximum value:

1. Monthly Card ($4.99) ⭐⭐⭐⭐⭐

• Value: 3,000 crystals over 30 days (90 crystals/day + 300 instant)
• Equivalent: 10 pulls for $5 ($0.50/pull)
• Best for: Light spenders who want consistent income

2. First-time Bonus Packs ($9.99-$49.99) ⭐⭐⭐⭐

• Value: Double crystals on first purchase of each tier
• Example: $9.99 pack = 1,600 crystals (normally 800)
• Best for: One-time spenders boosting limited banner pity

3. Battle Pass ($9.99/season) ⭐⭐⭐⭐

• Value: 2,400 crystals + 10 Rescue Tickets + ascension materials
• Best for: Players who complete daily missions regularly

❌ Avoid: Direct Crystal Packs

Standard crystal packs ($19.99 for 1,600 crystals, $49.99 for 4,800 crystals) offer terrible value compared to Monthly Card. Never buy unless it's your first purchase with double bonus.

Spending Tiers

F2P ($0/month): Competitive in all PvE content. Can clear Nightmare Mode with planning using our team building strategies.

Dolphin ($10-30/month): Monthly Card + occasional Battle Pass. Guarantees 1-2 limited characters per year comfortably. Sweet spot for most players.

Whale ($100+/month): Can collect every limited character and pull for constellations (duplicates). Not necessary for content completion.

Frequently Asked Questions

How many pulls does F2P get per month?

Approximately 27-30 pulls/month from dailies, events, story, and achievements. This allows F2P players to hit pity (~90 pulls) every 3 months.

Should I pull for dupes (constellations)?

No, not for F2P players. New characters provide far more value than constellations (duplicates). Dupes offer minor stat boosts (5-10% damage increase), not worth 90-pull pity investment. Only whales should chase constellations.

When do limited banners run?

Limited banners typically run every 3-4 weeks for 2-3 weeks each. Check in-game news and official social media for announcements. Usually announced 1 week before banner starts.

Can I pull limited characters from Standard Banner?

No. Limited characters (e.g., Haru) are exclusive to their Limited Banners and never enter the Standard pool. If you miss them, you must wait for a rerun (typically 6-12 months later).

Is it worth pulling on weapon/equipment banners?

CZN currently has no weapon/equipment gacha. All gacha pulls are for characters only. Equipment is obtained through story, events, and crafting—making CZN much more F2P-friendly than games with equipment gachas.

What happens when I pull a duplicate character?

Duplicates unlock Constellation nodes that provide small stat boosts:

• Dupe 1: +5% ATK
• Dupe 2: +10% HP
• Dupe 3: Unlock special ability variation
• Dupe 4-6: Further stat increases

However, these bonuses are minimal. Focus on roster diversity over constellations.

How do I check my pity count?

In-game: Gacha menu → Banner → History tab → Count pulls since last 5-star

Manual tracking: Use community tools like CZN Pity Calculator (search CZN subreddit)

Should I save pity for specific banners?

Yes, if you're at 70+ pity on Limited Banner. If a limited character you don't want is currently featured, wait for the next limited banner to spend your guaranteed 5-star pity. Remember: 50/50 guarantee carries over between limited banners.
