Overview: What Makes the Dark Brotherhood Questline Special
The Dark Brotherhood in Oblivion is not just a series of fetch quests. It’s a narrative-driven guild arc combining stealth, moral ambiguity, and unique NPC interactions. From the moment you hear the first whispered contract to your final audience with the Night Mother, the quests emphasize stealth, planning, and timing. The atmosphere in the Dark Brotherhood Sanctuary, the presence of Lucien Lachance, and the ritual of the Black Sacrament make it one of the most iconic Oblivion quests. Expect assassination contracts that test your sneaking, social navigation in Cyrodiil, and some memorable moral choices.
How to Join the Dark Brotherhood: Step-by-Step
Joining the Dark Brotherhood guild in Oblivion requires following a specific sequence. Here’s a compact walkthrough with tips to avoid common pitfalls.
- Step 1: Perform the Black Sacrament – To attract the attention of the Dark Brotherhood, perform the Black Sacrament at night in a secluded area. Bring a human heart and follow the ritual instructions. Ensure you’re not seen; performing the ritual in town increases risk.
- Step 2: Wait for Lucien Lachance – After the Black Sacrament, the emissary Lucien Lachance may approach you in your sleep or through a dream. He will offer you a contract leading into the guild. Save frequently; RNG can delay contact.
- Step 3: Accept the Initiation Contract – Complete the initial assassination tasks Lucien assigns to prove your skill. Use stealth, poison, or ranged attacks to minimize confrontation. These early contracts also serve as a tutorial on how the guild operates.
- Step 4: Visit the Sanctuary – Once you prove yourself, you will be invited to the Dark Brotherhood Sanctuary. The Sanctuary is the hub where you receive assassination contracts, meet the Night Mother, and access unique gear.
Tip: Keep a spare save before performing the Black Sacrament and before meeting Lucien Lachance. That way, you can reset if an unexpected encounter breaks immersion or causes a bug.
Key Quests and Walkthrough: From Initiation to Final Contract
The dark brotherhood questline Oblivion includes a sequence of quests that escalate in both difficulty and storytelling. Below are the main quests you will encounter and how to approach them.
1. Initiation Tasks
- Complete assassination contracts assigned by Lucien Lachance. These introduce stealth mechanics and assassination contracts. Keep your Sneak and Marksman skills high for easy silent takedowns.
2. Sanctuary Missions
- Once inside the Sanctuary, you’ll receive more complex contracts involving travel across Cyrodiil. Use fast travel to save time but be mindful of map locations and guards in smaller cities like Bruma or Cheydinhal.
3. The Night Mother’s Role
- As you progress, you will witness the cult-like reverence for the Night Mother. Story quests around her deepen the guild’s lore and present choices that impact your standing in the Dark Brotherhood guild.
4. Final Contracts and Conclusions
- The culminating missions typically lock in your reputation. You might be asked to eliminate key figures in Cyrodiil or face moral dilemmas that shape the final narrative. Plan your equipment and save often before each final contract.
Example: On a mid-game contract, you may be asked to assassinate a noble in the Imperial City. Use a combination of potion-based invisibility, stolen keys, and timed poison to ensure a clean execution without alerting city guards. These missions reward patience more than brute force.
Best Strategies for Assassination Contracts
Success in the Dark Brotherhood quests depends on smart preparation. These assassination contracts are not just about killing; they are about precision and craft.
- Skill focus: Maximize Sneak, Marksman, and Blade or Security for lockpicking. Illusion magic (Invisibility, Chameleon) can be a game-changer.
- Gear: Equip light armor for mobility. Dark Brotherhood armor sets enhance stealth and roleplay. Store heavy items to stay nimble during infiltrations.
- Potions and Poisons: Bring Chameleon or Invisibility potions and paralysis or damage-over-time poisons. Poisons applied to dagger strikes allow for silent kills without blood trails to alert guards.
- Entry methods: Always check the environment for alternate entries. Roof access, cellars, and servants’ doors can save you from head-on fights.
- Escape plan: After a contract, have a route planned to exit the area quietly. Shadowing alleys or waiting with a hidden mount can prevent detection.
Tip: If you prefer a non-lethal approach to infiltration, use distractions like throwing apples or triggering minor traps to move NPCs away before striking.
Dark Brotherhood Armor, Rewards, and Unique Loot
Progressing through the Dark Brotherhood questline awards exclusive gear and items that enhance assassin builds. Here’s what to expect and how to prioritize rewards.
- Dark Brotherhood Armor Set: This set is ideal for stealth characters—lightweight with bonuses to sneak and critical hits. It also enhances roleplay value by reinforcing your identity as a member of the guild.
- Unique Weapons: Certain contracts or final missions can yield unique daggers or poisons. These are often superior for finishing moves in assassination contracts.
- Gold and Influence: Completing contracts increases your standing with the guild and can unlock stronger assassination contracts with higher payouts.
- Titles and Sanctuary Perks: As you rise in the Dark Brotherhood guild, you’ll access special rooms in the Sanctuary and the respect of fellow assassins.
Example: Completing a high-tier contract might reward a uniquely enchanted dagger that deals bonus damage to humanoids, making future stealth kills faster and safer.
Tips, Tricks, and Common Pitfalls
These are practical tips to smooth your journey through the Dark Brotherhood quests in Oblivion, plus traps to avoid.
- Save Often: The Dark Brotherhood questline can be delicate. Save before major contracts, before triggering the Black Sacrament, and before any conversation with Lucien Lachance.
- Avoid Public Killing: Killing guards or prominent NPCs in public can escalate to hostile city-wide alerts and make future missions harder.
- Keep a Low Profile: Don’t join multiple factions whose goals directly conflict. The Thieves Guild and the Dark Brotherhood can overlap in playstyle, but loyalty matters for quest outcomes.
- Watch for Bugs: Oblivion has aged gracefully but still has bugs. If a quest fails to update, reload a previous save or consult community patches if you play on PC.
- Roleplay Choices: The Night Mother’s presence and the cult rituals invite roleplay. Decide early if your character is ruthless, principled, or conflicted—this choice makes the story more engaging.
Advanced Examples and Playstyles
Here are three recommended playstyles for maximizing your effectiveness and enjoyment in the Dark Brotherhood:
1. The Silent Blade (Stealth Assassins)
- Core skills: Sneak, Blade, Marksman, Security.
- Approach: Enter unseen, deliver a critical dagger blow, then vanish. Prioritize poisons and enchantments that increase sneak attack damage.
2. The Ghost Mage (Magic and Illusion)
- Core skills: Illusion, Conjuration, Light Armor.
- Approach: Use Invisibility, Calm, or Frenzy spells to manipulate targets, then finish the contract with a bound dagger or summoned minion.
3. The Trickster (Hybrid and Opportunist)
- Core skills: Alchemy, Speechcraft, Sneak.
- Approach: Use speech to gain access, potions to incapacitate, and stealth to finish jobs cleanly. This build excels at social infiltration.
