Black HoleBlack Hole is the primary weapon. Size Tome and Duration Tome are wiki-confirmed for Black Hole. Cooldown Tome is wiki-confirmed for Spaceman specifically. Spicy Meatball chains explosions through Black Hole clusters. Demonic Soul stacks damage from kills that Spaceman generates at an accelerated rate through his XP passive.

Cooldown Tome| Phase | Pickup | Why |
|---|---|---|
| 0-4 min | Black Hole + Size Tome | Black Hole upgrades with Size and Duration per the wiki. Size Tome widens the pull radius, dragging more enemies into the cluster per black hole. The wiki confirms area damage and battlefield control are the goal. |
| 4-8 min | Duration Tome + Cooldown Tome | Duration Tome is wiki-confirmed for Black Hole via the Stats wiki. Duration keeps each black hole active longer. Cooldown Tome is wiki-confirmed for Spaceman specifically, maximising Black Hole uptime. |
| 8-12 min |  Spicy Meatball + second weapon | Spicy Meatball gives a 25% chance of an explosion on every hit. Black Hole clusters enemies tightly. One hit in the cluster triggers a chain explosion through all nearby enemies. The wiki confirms explosion radius scales with Size, the same stat that boosts Black Hole. |
| 12+ min |  Demonic Soul + legendary items | Demonic Soul gives stacking damage per kill. Spaceman's XP Gain passive levels him faster, generating more kills over a run. More kills means faster Demonic Soul stacking on top of Damage Tome scaling. |
This variant combines Spaceman's XP passive with XP Tome and Cursed Tome for aggressive level scaling. The XP Tome wiki confirms Cursed Tome stacks with XP multipliers: more enemies means more XP orbs which means greater benefit from XP Gain bonuses. Spaceman's passive adds to the XP Gain stack every level. Higher levels mean more weapon and Tome upgrades, making each run scale faster into lategame.
Black Hole Aura
Flamewalker Frostwalker
XP Tome Size Tome Cooldown TomeThree weapons, three tomes. Black Hole handles crowd control, Aura covers passive close-range damage, Firestaff adds projectile AoE on top of the clustered enemies. Size Tome first to maximise the Black Hole pull radius. Cooldown Tome second for more Black Holes per minute. Forgiving because the Black Hole pull keeps enemies away from Spaceman while the passive provides steady XP to reach key Tome levels faster.
Black Hole Aura Firestaff Size Tome Cooldown Tome Duration TomeThe Spaceman wiki explicitly lists Cooldown upgrades as a core synergy to maximise Black Hole uptime. More Black Holes per minute means more groups pulled into clusters more frequently. Cooldown Tome is the primary quality-of-life investment for consistent battlefield control.
Spicy Meatball gives a 25% chance for each hit to trigger an explosion dealing 65% of that hit's damage to nearby enemies. Black Hole pulls all enemies into a tight cluster. One hit landing in that cluster triggers an explosion that hits every enemy in range, each with their own 25% chance to chain further. The explosion radius also scales with Size, the same Tome that boosts Black Hole.
Spaceman gains +1% XP Gain per level from the Quantum XP Theory passive. At level 50, he has 50% bonus XP Gain just from the passive, not counting XP Tome. Higher levels mean more Damage Tome upgrades, more weapon levels, and more chest items in equivalent time. This is Spaceman's core advantage in long runs.
The Stats wiki confirms Black Hole scales with Size and Duration. The Spicy Meatball wiki confirms its explosion radius also scales with Size. This means a single Tome investment in Size simultaneously widens the Black Hole's pull radius and the explosion radius of Spicy Meatball, making both more effective at once.
All three items are sourced from the wiki. Spicy Meatball is wiki-confirmed for AoE chain builds and scales with Size Tome. Demonic Soul is wiki-confirmed for high-kill runs. Credit Card Green benefits from Spaceman's faster levelling.
Spaceman requires completing 6 Challenges and having Black Hole unlocked.
Unlock Black Hole
Complete 6 Challenges Buy Spaceman from the Unlocks tabSpaceman is a strong crowd control character whose passive compounds quietly every level. Black Hole is considered one of the most powerful crowd control tools in the game per its wiki page. The XP passive means Spaceman reaches higher weapon and Tome levels in the same time as other characters, giving him better overall scaling. He has no bonus base stats, so the passive and Black Hole uptime are entirely responsible for his edge. Immune to fall damage.
