Deep Crafter Boss Guide: How to Beat Every Major Boss

2026-06-09·Boss Guides

Key Takeaways

  • The Void Titan (800m) is the hardest boss. You need full Titanium Gear + O2 Tank Mk3 + 5 O2 Candles minimum.
  • Bosses don't respawn. Each boss drops a unique crafting recipe. Kill them all to unlock every recipe in the game.
  • Every boss arena has O2 refill spots. Find them before starting the fight.

Stone Colossus (120m)

HP: 500. Attack Pattern: Ground slam (shockwave) → Charge → Ground slam.

Strategy: Stand near the arena edges. When it charges, dodge sideways (the charge doesn't track). Hit its back 4-5 times while it recovers. Repeat 6-8 cycles.

Crystal Guardian (250m)

HP: 1,000. Attack Pattern: Crystal shard spray (ranged) → Teleport → Melee swipe.

Strategy: Hide behind Crystal formations during the shard spray (they absorb the projectiles). After the teleport, it appears behind you — immediately turn and attack 2-3 times.

Lava Wyrm (400m)

HP: 2,000. Attack Pattern: Surface → Fire breath (cone AoE) → Submerge → Surface at new location.

Strategy: Drink Fire Resist Potion before the fight. Stand on stone platforms (not near lava). When it surfaces, run perpendicular to its head to avoid the fire breath, then hit its exposed neck 3 times.

Abyssal Horror (600m)

HP: 3,500. Attack Pattern: Tentacle sweep → Dark beam → Summon Void Phantoms (×2).

Strategy: Kill the summoned Phantoms first (they're the real threat). Dodge the dark beam by standing behind pillars. Attack tentacles during the sweep recovery.

Void Titan (800m)

HP: 8,000. Attack Pattern: 4-phase rotating cycle. Phase 1: Melee strikes. Phase 2: Void lasers. Phase 3: Gravity inversion (ceiling becomes floor). Phase 4: All mechanics simultaneously.

Strategy: O2 management is the real challenge. The fight takes 8-12 minutes. Use O2 Candles between phases. Phase 3 is disorienting — focus on dodging, not attacking. Save Dark Matter Blade's special attack for Phase 4.

FAQ

Q: Can I refight bosses?

A: No. Each boss is a one-time encounter. Make sure you're prepared before entering the arena.

Q: What boss has the best drop?

A: Void Titan drops the 'Void Core,' which unlocks Dark Matter crafting — the best gear tier.
