Ascend to ZEROThis build tier list ranks the most effective chip compositions in Ascend to ZERO from S tier (meta-defining) to C tier (niche or suboptimal). Unlike the avatar tier list which evaluates characters, this list evaluates the build archetypes — specific combinations of skill chips, stat chips, devices, and gadgets that create synergistic strategies.
How Builds Are Evaluated
Builds are rated on their synergy effectiveness — how well the chip components combine to create outcomes greater than the sum of their parts. A build with 5 individually strong chips that do not synergize ranks lower than a build with 5 moderately strong chips that multiply each other's effects.
| Evaluation Factor | Weight | What It Measures |
|---|---|---|
| Damage Output | 30% | Maximum damage per second and per burst |
| Timer Efficiency | 25% | Net timer gain per encounter |
| Synergy Score | 25% | How well components multiply together |
| Consistency | 20% | How reliably the build performs across runs |
S Tier Builds
S1: Blossom Blade Sword Stack
The strongest build in the game. Stack 4+ sword skill chips on Blossom Blade for multiplicative melee damage, add damage stat chips to amplify the multiplied base, and equip burst gadgets for time-resume double-dip damage.
Build composition:
- 4x Sword Skill Chips
- 2x Damage Stat Chips (+10-20% total)
- 1x Extra Time Device
- 1x Extra Resurrection Device
- 1x Burst Gadget
Why S tier: Sword chips stack multiplicatively (not additively), meaning 4 sword chips create approximately 4x-6x base damage. Damage stat chips amplify this multiplied base. The combined effect is a single time-resume slash that can eliminate entire enemy groups. The weakness is low defense — every hit costs precious timer seconds. See our Chip Build Strategy for the full build breakdown.
S2: Frost Moon Drone Swarm
The strongest area control build. Stack device chips that enhance drone count, damage, and range. Drones deal passive damage while the player focuses on movement and timer management. Gadgets that create AOE effects on time-resume add to the drone swarm's damage output.
Build composition:
- 4x Drone Device Chips
- 2x Damage Stat Chips
- 1x Extra Time Device
- 1x AOE Gadget
- 1x Trap Gadget
Why S tier: Drone swarms scale compoundly — each device chip adds both damage and an additional drone, creating exponential area coverage. In late-run stages with dense enemy populations, drone swarms clear rooms passively while the player navigates. The weakness is a very slow early game before drones are established.
A Tier Builds
A1: Golden Gunslinger Precision Range
A safe, consistent build that maintains maximum range. Gun skill chips provide steady DPS, while projectile speed stat chips ensure hits land before enemies close the distance. The gap-creator time-resume ability serves as both offensive and defensive tool.
Build composition:
- 3x Gun Skill Chips
- 2x Projectile Speed/Damage Stat Chips
- 1x Extra Time Device
- 1x Extra Resurrection Device
- 1x Projectile Gadget
Why A tier (not S): The gun's linear scaling provides consistency but lacks the exponential ceiling of sword or drone builds. Timer preservation is excellent (few hits taken), but the slower clear speed means less timer extension per room.
A2: Chrono Child AOE Burst
A burst-oriented build for Chrono Child that maximizes the AOE explosion radius and damage. AOE skill chips plus explosion radius stat chips create a large damage zone on every time-resume.
Build composition:
- 3x AOE Skill Chips
- 2x AOE Radius Stat Chips
- 1x Extra Time Device
- 1x Burst Gadget
Why A tier: The AOE burst is effective and forgiving, but Chrono Child's balanced scaling prevents the dramatic late-run power spikes that S tier builds achieve. This build is optimal for Chrono Child specifically but cannot match Blossom Blade's ceiling.
B Tier Builds
B1: Mixed Chip Generalist
A non-specialized build that picks up whatever chips are available rather than committing to a specific type. While flexible, this build lacks the synergy that makes specialized builds powerful.
Why B tier: Without the multiplicative stacking of same-type chips, damage output grows linearly rather than exponentially. The build is viable but significantly underperforms compared to specialized builds.
B2: Defense-Heavy Tank
A build focused on defense stat chips and damage-reduction devices, attempting to minimize timer loss per hit. While this approach reduces mistakes' impact, it sacrifices the damage output needed for efficient timer extension.
Why B tier: Defense builds reduce timer drain per hit but do not increase timer extension per kill. The net timer gain per encounter is lower because you kill enemies more slowly. Time freeze already prevents most damage, making defense investment less valuable than damage investment.
Build Tier List with Specific Chip Compositions
The build tier list evaluates complete chip compositions rather than individual chip values. Each build is a specific combination of skill, stat, device, and gadget chips:
S Tier Builds:
| Build | Avatar | Chips | Gadget | Why S Tier |
|---|---|---|---|---|
| Sword Stack | Blossom Blade | 4 sword, 2 damage stat, 2 device | Burst | 6x multiplier × damage amplification × burst = highest output |
| Drone Swarm | Frost Moon Hacker | 4 drone device, 2 damage stat, 2 device | Trap | Compound scaling creates overwhelming area control |
A Tier Builds:
| Build | Avatar | Chips | Gadget | Why A Tier |
|---|---|---|---|---|
| Precision Range | Golden Gunslinger | 3-4 gun, 2 projectile/damage stat, 2 device | Projectile | Consistent DPS, safe combat |
| AOE Burst | Chrono Child | 3-4 AOE, 2 radius/damage stat, 2 device | Burst | Forgiving centered damage, large AOE |
B Tier Builds:
| Build | Avatar | Chips | Gadget | Why B Tier |
|---|---|---|---|---|
| Mixed Generalist | Any | 2-3 mixed skill, 2 stat, 2 device | Any | Flexible but no synergy; linear scaling |
| Defense Tank | Any | 2 defense stat, 2 device, 2 defense device | Shield | Reduces timer drain but not kills |
C Tier Builds:
| Build | Avatar | Chips | Gadget | Why C Tier |
|---|---|---|---|---|
| No-Gadget Build | Any | Full chip slots, no gadget | None | Missing 1.5-3x combo multiplier |
| Full Device Stack | Any | 6 device chips, 0 skill/stat | Any | Maximum safety, minimum damage |
The gap between S and A tier is larger than the gap between A and B tier. A fully optimized Sword Stack build deals approximately 2-3x more damage per resume than a Precision Range build. This damage difference translates to significantly faster room clears and more timer extension. For individual chip rankings, see our Chip Tier List.
Build Tier List Impact of Time Machine Investments
Time Machine upgrades effectively shift build tier rankings by providing permanent bonuses that apply to every run:
| Build | Tier (0 Keys) | Tier (200 Keys) | Tier (500+ Keys) | Key Upgrades |
|---|---|---|---|---|
| Sword Stack | S | S+ | S+ (dominant) | Starting time, damage |
| Drone Swarm | A | A+ | S | Starting time, XP |
| Precision Range | A | A | A+ | Starting time, damage |
| AOE Burst | A | A | A | Starting time, XP |
| Mixed Generalist | B | B+ | A- | Starting time, XP |
| Defense Tank | B | B | B+ | Defense, starting time |
Starting time is the universal tier-booster because it gives every build a larger early-game buffer. This is especially impactful for Frost Moon Hacker (whose early game is its weakness) and Blossom Blade (whose glass cannon nature needs buffer). 200 Zero Keys invested in starting time moves Hacker from A to A+ and Blade from S to S+. For the full upgrade path, see our Bunker Upgrade Guide.
Build Tier List Practical Takeaways
The key practical takeaways from this build tier analysis:
-
Specialization beats generalization. S-tier builds commit to one chip type and maximize synergy. B-tier builds spread across types and lose the compounding effect.
-
The gadget is not optional. A build without a gadget is effectively one tier lower. Finding a synergistic gadget early transforms an A-tier build into S-tier.
-
Device chips provide the safety floor. Even S-tier builds benefit from 1-2 device chips. Glass cannon builds without devices frequently die before reaching late-game stages.
-
The inflation model rewards early decisions. The first 3 chip pickups determine your build trajectory. Choose wisely in the first 5 rooms and your late-run performance reflects those choices.

Frequently Asked Questions
Can I mix build archetypes?
Mixing chip types reduces synergy. A build with 2 sword chips and 2 gun chips has neither the multiplicative melee scaling nor the consistent ranged DPS of a specialized build. The only effective "hybrid" is Chrono Child's AOE build, which naturally benefits from multiple chip types.
What if I cannot find the chips for an S tier build?
Chip drops are semi-random. If you cannot find 4 sword skill chips for the Blossom Blade Sword Stack, prioritize the first 2-3 sword chips and supplement with damage stat chips. An incomplete S tier build still outperforms a complete B tier build. See our Chip Build Strategy for adaptive build decisions.
How do gadgets affect tier rankings?
Gadgets that synergize with the build's core mechanic (burst gadgets for sword builds, AOE gadgets for drone builds) effectively raise the build's tier by one level. Gadgets that do not match the build's mechanic have minimal impact. For detailed gadget analysis, see our Weapon & Gadget Guide.
