Chaos Zero Nightmare Season 5 Combatant Selector Priority Guide

Use your Season 5 Combatant Selector to acquire an unowned, universal support unit before considering damage dealers or duplicate copies. Securing foundational utility gives your account the flexibility needed for multi-team Sortie encounters, while duplicate copies offer narrow stat upgrades that do not solve roster bottlenecks.

Hold the selector ticket in your inventory until you finish your seasonal banner pulls. If you summon an unowned unit naturally, you can apply the ticket to your remaining roster deficit without wasting a choice.

Selector Priority Tier List

Priority Tier	Combatants	Role	Ideal Account Scenario
Top Priority (Universal Support)	Mika, Selena	Sustain & Draw / Squad Damage Buffer	Lacking an engine for healing, card cycling, or multi-team offensive buffs
Secondary Priority (Core Carry)	Hilde, Haru	Multi-Hit Physical / Single-Target Burst	Possessing stable supports but lacking a reliable primary damage dealer
Situational (Archetype Specialist)	Hugo, Clara, Kayron	Control & Defense / Debuffs / Burn Brawler	Needing specific encounter counters and already owning standard core units
Lowest Priority (Duplicate Shards)	Any owned unit	Evolutionary Stat Boosts / Passive Upgrades	Owning every standard combatant across both primary and secondary squads

First Priority: Universal Supports (Mika or Selena)

Support combatants remain viable across multiple seasonal meta shifts and fit into almost any card composition. If your roster lacks either of these two units, choose them first.

Mika (Sustain and Card Cycling): Pick Mika if your teams struggle with survival in prolonged encounters. She provides low-cost healing cards, cleanses targeted debuffs, and cycles cards so your main striker draws burst combos consistently.
Selena (Universal Damage Amplification): Pick Selena if your survival is adequate but you struggle to meet challenge-mode turn limits. She supplies squad-wide attack boosts and card manipulation that work with physical, elemental, and hybrid archetypes.

Second Priority: Dedicated Carries (Hilde and Haru)

Select a striker only if your support core is stable and your account cannot field an effective damage carry for gear farming stages.

Hilde: The top standard damage dealer choice. Her multi-hit cards and aggressive scaling make her effective in both single-target boss fights and multi-enemy waves without requiring specialized team setups.
Haru: A focused alternative for accounts that specifically require sustained, high-output single-target boss damage.

Skip these options if you already own premium carries such as Rossweisse, Fei, or Tenebria. Dedicated damage dealers are replaced more frequently than universal buffers and healers.

Situational Specialists

Only select niche units if your core support and carry roles are filled and you require a specific tactical tool for specialized encounters:

Hugo: Provides shields, disruption, and front-row survivability against heavy burst bosses, though his personal damage output is low.
Clara: Supplies turn manipulation and targeted debuff cycling for control-heavy card strategies.
Kayron: Acts as a self-sufficient brawler with burn mechanics, but requires specific support setups to match the clear speed of standard carries.

When to Choose Duplicates

Selecting a duplicate unit is only justified if you already own every high-impact standard combatant. Duplicates provide evolutionary threshold upgrades and localized stat boosts.

If you must choose a duplicate, invest in supports like Mika or Selena to enhance squad-wide utility and energy efficiency rather than investing in minor stat gains for an individual striker.
