Introduction
Baldur’s Gate 3 (BG3) is a game filled with deep storytelling, complex mechanics, and challenging boss fights. Among its most formidable foes is the Netherbrain, the final boss that requires careful strategy to defeat. However, speedrunners have discovered ways to obliterate it in just 10 seconds—without needing a full party!
In this guide, we’ll break down the exact steps, gear, and strategies to achieve this insane feat. Whether you’re a speedrunner or just looking for the most efficient way to finish the game, this method will save you hours of combat.
Why This Strategy Works
The Netherbrain fight is designed to be a multi-phase battle, but with the right setup, you can skip all mechanics and instantly kill it. The key lies in:

- Maximizing burst damage
- Exploiting game mechanics
- Using specific gear and abilities
This method is solo-friendly, meaning you don’t need to rely on companions, making it perfect for speedruns or challenge runs.
Required Setup
1. Character Build
The best class for this strategy is the Sorcerer (Storm Sorcery) due to its high burst damage potential. However, a Fighter (Eldritch Knight) or Paladin (Oathbreaker) can also work with slight adjustments.
Key Attributes:
- Charisma (20+) – For spellcasting effectiveness
- Constitution (16+) – To survive initial hits
- Dexterity (14+) – For initiative
2. Essential Spells & Abilities
- Magic Missile (Upcast to Level 6)
- Quickened Spell (Metamagic)
- Haste (Either from potion or spell)
- Disintegrate (Optional but useful for extra damage)
3. Must-Have Gear
- Markoheshkir (Legendary Staff) – Doubles spell damage
- Spellcrux Amulet – Restores spell slots mid-fight
- Gloves of the Automaton – Guarantees critical hits
- Helm of Arcane Acuity – Boosts spell accuracy
4. Potions & Consumables
- Potion of Speed (Haste without concentration)
- Elixir of Bloodlust (Extra action after kill)
- Scroll of Disintegrate (Backup damage)
Step-by-Step Execution
Phase 1: Pre-Battle Preparation
- Enter the battle solo – Dismiss all party members to avoid AI interference.
- Pre-buff with Haste – Use a Potion of Speed to avoid concentration checks.
- Position yourself near the Netherbrain’s weak point – This ensures minimal movement.
Phase 2: The 10-Second Kill
- Open with Quickened Magic Missile (Level 6) – This guarantees multiple high-damage hits.
- Follow up with Disintegrate (if available) – This bypasses resistances.
- Use Action Surge (if Fighter) or another high-damage spell – Maximize burst.
- Trigger Bloodlust (if using Elixir) – Get an extra action for cleanup.
Result: The Netherbrain’s health bar instantly depletes before it can even react!
Why This Is the Fastest Method
- No Party Needed – Fewer characters mean fewer turns, streamlining combat.
- No Phases Skipped – The Netherbrain doesn’t get a chance to activate mechanics.
- Reliable & Repeatable – Works on all difficulty levels.
Alternative Strategies
If you don’t have the exact gear, here are backup options:
- Barbarian (Berserker) + Tavern Brawler – Throw weapons for massive damage.
- Rogue (Assassin) + Sneak Attack Crits – One-shot potential with the right setup.
Conclusion
Destroying the Netherbrain in 10 seconds solo is not only possible but incredibly satisfying. With the right build, gear, and execution, you can bypass the entire final battle and claim victory in record time.
