Gacha System
The main way you acquire characters in Chaos Zero Nightmare is through its gacha system. You can acquire Combatants, who appear in battle, or Partners, who can be equipped to a Combatant (like a weapon in other gacha games). Combatants can be 4-star or 5-star in rarity, while Partners can be 3-star, 4-star, or 5-star.
Rescues
Rescues are what Chaos Zero Nightmare calls its gacha pulls. To pull on its banners, or rescuing, you will use Rescue Anchors (standard pulls) or Rescue Amplifiers (rate-up pulls).
- 160 Crystals = 1 Rescue Anchor/Amplifier.
- Rescue Anchors are used for the Special Rescue Request (beginner banner), Combatant Rescue (standard Combatant banner), and Partner Rescue (standard Partner banner).
- Rescue Amplifiers are used for rate-up banners.
Also, you are guaranteed to get a 4-star Combatant or Partner every 10 pulls.
