Tier List of Partner Characters in Chaos Zero Nightmare
Tier Criteria
| criterion | detail |
| Ego Skill Effect & Cost | Consider the strength of the skill and the amount of energy used (EP). |
| Passive Effect | The Partner’s add-on ability can work well with multiple characters and doesn’t require complicated conditions. |
| Accessibility | Ease of use and capability in common situations Even if it is not rare, it has a high chance of being in the Tier if the performance is good. |
Meaning of Tier
Tier S is an indispensable group of partners for high-level teams in both PvE and PvP modes because they have skills that work well without relying on too much conditioning, and can synergize with the main characters in multiple streams such as Khalipe, Nia, and Cassius.
Tier A is suitable for players who don’t have a high-level partner yet, as they are interchangeable in many teams, especially Kiara and Asteria, which have heavy damage and simple conditions.
Tier B is suitable for team-specific uses, such as serial bosses or teams that require specialized buffs, but it is not suitable for all situations.
Tier C is a highly restrictive Partner, uses too much EP, or gives inefficient results compared to other Tiers.
