Chaos Zero Nightmare: In-Run vs Out-of-Run Combatant Tier Guide

In Chaos Zero Nightmare, combatants must be evaluated across two distinct environments: active in-run roguelike exploration and fixed out-of-run endgame trials. A unit's ranking changes depending on whether they must navigate random floor drafts or execute a fully refined, exported save deck. Before committing selector tickets or breakthrough resources, determine whether your account needs baseline survivability to clear roguelike content or burst damage to climb raid leaderboards.

In-Run Exploration vs. Out-of-Run Raid Ceilings

Combat performance in Chaos Zero Nightmare splits based on deck consistency and stage structure:

In-Run Performance (Chaos Exploration, Great Rift): Evaluates how effectively a combatant performs starting from floor one. In-run success requires handling starter deck bloat, randomized card drafts, unpredictable epiphanies, and immediate early-stage enemy pressure. Units excel here when their baseline kits provide self-sufficient defense, direct area-of-effect damage, or reliable sustain without relying on specific card deletions or rare neutral relics.
Out-of-Run Performance (Total War, Galactic Disaster, Boss Trials): Evaluates combatants using exported, fully optimized save decks in fixed encounters. Drafting variance is completely absent. Combatants enter battle with compressed 10-to-12 card decks, guaranteed duplicate upgrades, and refined epiphany paths. This format prioritizes high burst multipliers, action point generation loops, and rapid one-turn setups over defensive attrition.

Main Combatant Archetypes

Main carries exhibit substantial divergence between early exploration stability and endgame score ceilings.

Combatant Archetype	In-Run Drafting Strength	Out-of-Run Boss Ceiling	Primary Role and Kit Behavior
Dual-Apex Carries	Very High	Exceptional	Possess strong base damage to clear early floors reliably, scaling into high burst once their decks are compressed.
Early Floor Stabilizers	High	Moderate	Offer high base shields and sustain to navigate roguelike hazards safely, but lack single-turn multiplicative scaling.
High-Ceiling Combo Carries	Low to Moderate	Top Tier	Struggle in early floors due to starter card bloat and dead draws, but reach unmatched burst once low-value cards are purged.

Dual-apex carries offer the safest investment across all modes. Their core skills feature high enough base numbers to clear early sectors and mid-bosses without heavy setup, while their mechanics scale directly with late-game damage multipliers and multi-hit triggers.

Combo-reliant carries experience the opposite trajectory. In early floors, unrefined strike and defend cards dilute their hands, slowing down card cycling and increasing turn counts and sanity loss. However, if navigated safely through late-stage shops to purge excess cards and secure target epiphanies, their exported save decks dominate high-difficulty raid rankings.

Sub-Combatant Utility

Sub-combatants are judged by how effectively they empower the main carry without consuming excessive action economy or clogging card draw.

Universal Action and Resource Buffers

Support units that generate action points, accelerate card draw, and provide generic damage buffs maintain top-tier value in both in-run and out-of-run modes. Extra action points and draw cycling mitigate poor card drafts during exploration runs. In exported raid teams, these same mechanics let your main carry cycle directly into their highest-impact cards every turn.

Defensive Tanks and Niche Enablers

Defensive units exhibit heavy ranking divergence between modes:

In-run crawling: High value. Taunts, barriers, and damage mitigation protect party health and sanity across long, multi-floor runs.
Out-of-run raids: Low value. Boss ranking challenges prioritize minimal turn counts and high burst output, making pure damage mitigation less useful than secondary offensive buffers or vulnerability debuffers.

Building an Out-of-Run Save Deck

Exporting a top-tier raid profile requires drafting specifically to overcome early-run weaknesses:

Prioritize early tempo over long-term synergy: In the first two sectors, draft raw damage and low-cost survival cards to stay alive. Surviving early encounters ensures you reach the shops and elite nodes needed to complete your build.
Aggressively purge basic cards: Use rest sites and merchant encounters primarily for card removal. Trimming basic starter cards down to a lean 10-to-12 card deck is essential for out-of-run consistency.
Draft around fixed team relics: Avoid situational cards that your team cannot trigger consistently. Select card upgrades and epiphanies that multiply your primary carry's damage type.

How to Allocate Selectors and Breakthroughs

Direct your account resources according to your current progression hurdle:

Choose in-run carries and universal buffers if you struggle to clear Great Rift runs or frequently wipe before reaching deep shop nodes. Consistent exploration clears secure your weekly farming progression.
Choose high-ceiling combo carries and offensive buffers if you can already clear roguelike content reliably. Investing breakthroughs into multiplicative damage dealers will maximize your ranking rewards in Total War and seasonal boss events.
