- Become Blackhole celestials are every devourable body from asteroids to stars.
- Target priority rule: crush clusters before solos for burst mass gains.
- Best early targets: rock clusters and debris fields, not isolated boulders.
- Late-game rule: save planets and high-mass stars for post-upgrade builds.
- Key stat: fragment yield per crush decides your growth speed at every stage.
Celestials Overview: What You Can Devour
In Become Blackhole, celestials are the cosmic bodies that fuel your growth from a speck of dust into a black hole. Each category — asteroid, moon, planet, and star — unlocks at a specific mass threshold, and each offers different fragment yields and crush difficulty. Choosing the right target at the right stage is the single biggest factor in how fast your mass bar fills.
The game's core loop is simple: find a cluster, shatter it, absorb the fragments, and move on. But every celestial type behaves differently, and treating them all the same wastes enormous amounts of time.
| Celestial Category | Unlock Stage | Typical Yield | Crush Difficulty | Best Approach |
|---|---|---|---|---|
| Dust & Debris | Dust stage | Low, passive | None | Continuous absorption while moving |
| Asteroids & Rocks | Asteroid stage | Medium, burst | Easy | Break clusters, collect fragments |
| Moons & Terrain | Moon stage | Medium-high | Moderate | Wide loop sweeps over structures |
| Planets & Landscapes | Planet stage | High | Moderate | Gravity pull loose objects first |
| Stars & Planetary Bodies | Star stage | Very high | High | Save for upgraded gravity radius |
Anything larger than your current form cannot be consumed. Check the size indicator before committing to a route — bouncing off an oversized target kills your momentum.
Celestial Types Compared: Yield vs. Effort
Not all celestials are worth your time at every stage. The most efficient players constantly weigh fragment yield against travel time and crush effort. These four categories define the mid-to-late game.
Asteroid Clusters
- Best for: Asteroid-stage players
- Yield: medium, but spawns dozens of fragments at once
- Risk: low — nothing in these fields threatens you
- Verdict: highest mass-per-second early on
Moon Terrain & Structures
- Best for: Moon-stage sweeps
- Yield: medium-high from structures and terrain features
- Risk: low, but requires route planning
- Verdict: excellent when chained in loops
Planets & Biomes
- Best for: Planet-stage, post-upgrade builds
- Yield: high — hills, buildings, entire biomes
- Risk: wasted potential if crushed too early
- Verdict: biggest single-stage jump in growth speed
Stars & Planetary Bodies
- Best for: Star stage, end of each zone
- Yield: very high, planetary-scale mass
- Risk: slow to strip without upgraded intake
- Verdict: save for last in each zone for a smooth curve
| Celestial Target | Mass per Crush | Fragment Count | Travel Value | Priority |
|---|---|---|---|---|
| Loose dust fields | Low | N/A (direct absorb) | ★★★★★ | Always collect in transit |
| Solo asteroid | Low | Few | ★★ | Skip unless adjacent |
| Asteroid cluster | Medium | Dozens | ★★★★ | Top early priority |
| Moon structure | Medium-high | Many | ★★★ | Sweep in loops |
| Dense planet biome | High | Very many | ★★ | Save for upgrades |
| Star / planetary body | Very high | Massive | ★★ | Zone finale target |
Players often rush dense planet zones the moment they unlock planet form. Strip them in seconds instead by waiting until your gravity radius and absorption speed are upgraded — the same zone yields far more mass per minute later in a run.
Step-by-Step: Optimal Celestial Crushing Route
This route maximizes fragment intake at every stage of the dust-to-black-hole chain. Follow it in order during each run.
Open With Debris Fields
As dust, keep moving through scattered material. Never stop — passive dust collection only pays while in transit toward the first rock cluster.
Break Your First Asteroid Cluster
At asteroid form, head straight for grouped rocks. Shattering a cluster spawns dozens of fragments at once, giving a mass burst that passive collection cannot match.
Loop Moon Structures in Circles
At moon form, sweep terrain features in wide circular loops so destroyed debris funnels naturally into your gravity field. No backtracking required.
Drag Before You Crush on Planets
At planet form, use gravity pull to drag loose objects toward you before crushing stationary terrain. Keep your absorption queue full at all times.
End Each Zone at the Star
Consume the highest-mass target last, positioned near the zone exit. You enter the next area at full momentum with mass already banked.
Finishing a zone next to its exit means you start the next one at full momentum instead of crossing empty ground. Learn each map's exit positions relative to its biggest clusters.
How Upgrades Change Celestial Value
Star map upgrades reshape which celestials are worth targeting. Absorption speed and gravity radius are the two nodes that compound across every future run — once upgraded, previously mediocre targets become efficient.
| Upgrade | Effect on Celestials | Value Rating |
|---|---|---|
| Absorption Speed | Faster fragment intake at every stage | ★★★★★ |
| Gravity Radius | Larger pull; cleans debris fields with less movement | ★★★★ |
| Movement Speed | Faster routing between clusters | ★★★ |
| Crush Power | Breaks tougher targets sooner | ★★★ (situational) |
Priority order for most runs:
- Dump early points into absorption speed — it is never wasted.
- Add gravity radius second to clean clusters without precise movement.
- Take movement speed only after the first two are meaningful.
Every upgrade purchased on the star map persists across runs. A fully upgraded intake build strips planet zones in seconds that once took minutes, turning late-run celestials into your most efficient targets.
Celestial Farming Milestones:
- Crush first full asteroid cluster for a fragment burst
- Chain a complete moon-structure loop without backtracking
- Clear a planet biome entirely after gravity radius upgrade
- Finish a zone by consuming its star near the exit
- Reach black hole form and devour an entire map
FAQ
Q: What are celestials in Become Blackhole?
Celestials are all the devourable cosmic bodies in the game: asteroids, moons, planets, and stars. Each type unlocks at a different growth stage and offers different fragment yields when crushed.
Q: Which celestials should I crush first?
Target grouped clusters before isolated objects. Breaking an asteroid cluster spawns dozens of fragments at once, delivering far more mass per second than solo targets or passive dust collection.
Q: Should I save planets and stars for later in a run?
Yes. High-mass targets yield significantly more once your gravity radius and absorption speed are upgraded. Leaving dense zones for later in a run lets you strip them in seconds.
Q: Can I devour celestials larger than my current form?
No. Anything larger than your current form cannot be consumed. You must grow through the dust, asteroid, moon, planet, and star stages before the largest bodies become valid targets.
