Ascend to ZEROComplete enemy kill order guide for Ascend to ZERO. Threat assessment, priority targeting, time-efficient combat, and avatar-specific approaches. This guide covers which enemies to kill first and which to skip.
Overview of Enemy Priority Targeting in Ascend to ZERO
Not all enemies are equal threats in Ascend to ZERO. Some enemies drain your timer rapidly (Time Stealers), some attack during freeze (Time Glitchers), and some are efficient time sources that extend your run. Understanding which enemies to prioritize and which to skip is the difference between a run that reaches 100K+ and one that dies at level 500. Kill order matters because the timer mechanic means every second spent fighting the wrong enemy is a second lost from productive combat.
Key Points About Enemy Priority:
- Time Glitchers are the #1 kill priority — they attack during freeze and can kill you while time is stopped
- Time Stealers are the #2 priority — they drain your timer passively while alive
- Low-level enemies below your level are efficient time sources — they extend your timer when killed
- High-level enemies above your level are time-negative — they drain more time than they return
- Bosses are always worth fighting — they provide the largest timer extension and best chip drops

Core Mechanics Behind Enemy Priority
The timer system creates a natural enemy value hierarchy. Killing an enemy extends your timer by 1-3 seconds (regular) or 8-15 seconds (boss). Being hit by an enemy subtracts 2-8 seconds. Enemies above your level deal more timer damage and provide less extension; enemies below your level deal less damage and provide more extension. This level-difficulty relationship means your kill priority should adapt based on your current level relative to enemies in the room.
| Enemy Type | Timer Extension on Kill | Timer Damage Per Hit | Threat Level | Kill Priority |
|---|---|---|---|---|
| Time Glitchers | +2s | -5s (attacks during freeze!) | Critical | #1 — Always kill first |
| Time Stealers | +1s | -3s/s passive drain | High | #2 — Kill ASAP |
| Regular Enemies (below level) | +2-3s | -1-2s | Low | #3 — Efficient time source |
| Regular Enemies (above level) | +1s | -4-6s | Medium | #4 — Skip if possible |
| Bosses | +8-15s | -3-8s per hit | High (but high reward) | Always fight if timer allows |
Time Glitchers deserve special attention because they are the only enemy type that attacks during time freeze. If you freeze time and ignore nearby Glitchers, they will continue attacking while everything else is stopped. This can cost 5-10 seconds of timer per freeze cycle if Glitchers are not eliminated first. For Glitcher-specific strategy, see our Time Glitchers Deep Dive.
Enemy Level Relationship and Timer Value:
| Your Level vs Enemy | Timer Extension | Timer Damage | Net Value | Action |
|---|---|---|---|---|
| 2+ levels above | +3s | -1s | +2s net | Kill — positive time investment |
| 1 level above | +2s | -2s | Neutral | Kill if convenient |
| Same level | +2s | -3s | -1s net | Kill if no better targets |
| 1 level below | +1s | -4s | -3s net | Skip — time-negative |
| 2+ levels below | +1s | -6s | -5s net | Skip — severely time-negative |
This table shows the fundamental rule: fight enemies at or below your level, avoid enemies above your level. Under-level enemies are efficient time sources that extend your run. Over-level enemies drain more time than they return, making them counterproductive to fight. For the full enemy type breakdown, see our Enemy Types Encyclopedia.
Best Strategies for Enemy Priority Targeting
Enemy Priority Core Strategies:
-
Glitchers First, Always — Before any freeze cycle, scan for Time Glitchers in the room. Kill them during freeze or immediately after resume. They are the only enemy that can hurt you during frozen time.
-
Eliminate Time Stealers Early — Time Stealers drain your timer passively while alive. The longer they survive, the more timer you lose. Kill them within the first 3 seconds of room engagement.
-
Focus Under-Level Enemies for Timer Extension — Enemies below your level provide the best time return on combat investment. Prioritize these when your timer needs replenishment.
-
Skip Over-Level Enemies — Enemies above your level drain more time than they return. If you encounter over-level enemies, freeze to position past them rather than fighting. Move to the next room where enemies may be at your level.
-
Route to Boss Rooms When Timer Permits — Bosses are always the highest-value targets due to large timer extension and skill chip drops. Include bosses in your route whenever your timer buffer exceeds 15-20 seconds.
Avatar-Specific Priority Adjustments:
| Avatar | #1 Priority | #2 Priority | Room Strategy |
|---|---|---|---|
| Blossom Blade | Glitchers (dash-slash during freeze) | Stealers (melee burst) | Freeze, position in center, resume for AOE clear |
| Golden Gunslinger | Glitchers (concentrated volley) | Stealers (targeted shots) | Range-advantage: pick off threats from safe distance |
| Frost Moon Hacker | Glitchers (drone focus fire) | Stealers (drone coverage) | Deploy drones on threats during freeze |
| Chrono Child | Glitchers (center AOE) | Stealers (AOE splash) | Center positioning hits both types simultaneously |

Common Priority Targeting Mistakes and How to Avoid Them
| Mistake | Why It Happens | How to Fix It |
|---|---|---|
| Ignoring Time Glitchers | Focusing on closer/larger enemies | Glitchers attack during freeze — always kill first |
| Fighting over-level enemies | Not checking level difference | Skip over-level; they drain more time than they return |
| Skipping bosses | Fear of timer loss | Bosses are net-positive — learn patterns instead |
| Fighting enemies in contamination | Not prioritizing zone exit | Kill threats, then exit zone immediately |
| Not adapting kill order per room | Using same priority regardless | Assess room composition; adapt kill order |
The most common mistake is ignoring Time Glitchers because they are visually less prominent than regular enemies. Glitchers are small and fast, but they are the only enemy that attacks during freeze. One Glitcher left alive can cost 5-10 seconds of timer during a freeze cycle. Always scan for Glitchers before freezing time.
Advanced Priority Targeting Techniques
Threat-Adjusted Routing: Plan your room route based on enemy composition. If a room contains Time Glitchers and Time Stealers, prioritize that room early when your timer buffer is highest. Rooms with only regular enemies can be cleared later. This threat-adjusted routing minimizes the risk of encountering high-threat enemies with low timer.
Skip-and-Return: If you enter a room with over-level enemies and a boss, freeze time, position past the over-level mobs to the boss, kill the boss, then exit. The boss kill provides the timer extension needed to fight the over-level enemies on your return path. This technique maximizes reward while minimizing timer risk.
Timer-Aware Kill Switching: During combat, dynamically switch targets based on timer status. If your timer drops below 15 seconds, immediately shift to killing under-level enemies for timer extension rather than continuing to fight the current target. This mid-combat priority switch can save runs from timer death. For timer management, see our How to Extend Your Timer Guide.
Enemy Priority Targeting by Room Type
Different room types create different priority targeting requirements. The standard "Glitchers → Stealers → Standard" order shifts based on room composition:
Standard rooms (3-5 enemies, no hazards):
- Any Time Glitchers present → Kill first during freeze
- Time Stealers approaching → Kill second (prevent timer drain)
- Remaining standard enemies → Kill in any order
Contamination rooms (enemies + zone hazards):
- Time Glitchers → Kill first (prevent attacks during freeze)
- Aura Time Stealers inside zones → Kill second from outside zone
- Enemies inside zones → Kill from zone edge during freeze
- Enemies outside zones → Kill last (lowest risk)
Boss rooms (boss + add enemies):
- Elite Time Stealers (Phase 3 adds) → Kill immediately
- Boss → Damage during recovery windows
- Remaining adds → Kill between boss attack cycles
Dense swarm rooms (8-12 enemies, Stage 3-4):
- Time Glitchers → Kill first
- Aura Stealers → Kill from outside range
- Enemy cluster → Burst damage on resume (target cluster center)
- Scattered survivors → Clean up with ranged or drone fire
The key principle: always eliminate the threat that bypasses your safety tools first. Glitchers bypass time freeze. Stealers bypass your combat efficiency. Eliminate these before dealing with standard enemies that your freeze-burst cycle handles naturally. For more on specific enemy types, see our Enemy Types Encyclopedia.
Frequently Asked Questions
Which enemy should I kill first in Ascend to ZERO?
Time Glitchers are always the #1 kill priority. They are the only enemy type that attacks during time freeze, making them uniquely dangerous. If you freeze time with Glitchers nearby, they will continue hitting you while everything else is stopped. Kill Glitchers before freezing or immediately after resume. See our Time Glitchers Deep Dive for detection and elimination strategies.
Should I fight enemies above my level?
Generally no. Enemies above your level drain more timer per hit than they return on kill, making them net-negative time investments. The exception is if the over-level enemy is blocking your path to a boss room — in that case, freeze to position past the enemy and reach the boss. The boss kill timer extension compensates for the time lost avoiding the over-level enemy. See our Enemy Scaling Guide for level difference math.
How do Time Stealers affect my timer?
Time Stealers passively drain your timer at approximately 3 seconds per second while they are alive in the same room. The longer they survive, the more timer you lose. Kill Time Stealers within the first 3 seconds of entering a room. The +1s timer extension from killing them is small, but stopping the passive drain is critical. See our Time Stealers Counter Guide for details.
