100% Invisible Thief Build for Oblivion Remastered: One-Shot Everything from the Shadows
The Elder Scrolls IV: Oblivion Remastered, released in April 2025, has revitalized Bethesda’s iconic RPG, selling millions with its enhanced visuals, refined mechanics, and bundled DLCs like Shivering Isles and Knights of the Nine. Set in Cyrodiil, players wield unparalleled freedom to craft unique builds, and none is as devastating as the 100% Invisible Thief—a stealth juggernaut that one-shots enemies from the shadows using Sneak, Illusion, and a deadly dagger. This build, celebrated on X by users like @OdaruKEKW and on Reddit by u/SpeedyTamriel, leverages permanent invisibility, maxed Sneak, and critical hit multipliers to decimate everything from bandits to Mehrunes Dagon’s minions. Drawing from community strategies and web sources like UESP, GamesRadar, and IGN, this guide details how to create the ultimate Thief build, ensuring you dominate Oblivion Remastered without ever being seen.
Why a 100% Invisible Thief Build?
The Thief build thrives on Sneak’s 6x damage multiplier (3x for ranged) at Master level, amplified by invisibility from Illusion spells or enchantments, allowing undetected one-shots. Oblivion Remastered refines stealth mechanics, fixing the original’s clunky detection and enhancing shadow visuals, making sneaking smoother, per VG247. At Sneak 100, you’re nearly undetectable while invisible, and critical hits with daggers (base damage 12-15, enchanted to 50+) can deal 1000+ damage per strike, per UESP. X clips, like @FatalisReigns’ one-shot of an Arena Champion, showcase the build’s lethality, while Reddit’s u/LivingRaccoon calls it “the most satisfying power fantasy.” This build excels in the main quest, Dark Brotherhood, and Thieves Guild, turning you into Cyrodiil’s unseen reaper.
Building Your Thief: Race, Birthsign, and Class
Race: Khajiit
Khajiit are ideal for their +10 Sneak, +10 Acrobatics, and +5 Marksman, boosting stealth and mobility. Their Night-Eye power ensures perfect vision in dark dungeons, critical for sneaking, as noted by The Times of India. The Pellitine origin’s +10 Agility enhances Sneak precision and dagger accuracy. Khajiit’s +10 Speed aids quick escapes, though combat is avoided.
Birthsign: Shadow
Shadow grants Invisibility (60 seconds, once per day), providing early stealth without Magicka, per Game8. This outperforms The Thief (+10 Agility/Speed/Luck) for its immediate utility, saving gold on spells. Reddit’s u/SpeedyTamriel praises Shadow for “free stealth at level 1,” crucial for early quests like “Unfriendly Competition.”
Class: Custom Thief
A custom class optimizes stealth over the premade Thief. Choose Agility and Intelligence as favored attributes, with seven major skills:
Sneak: Enables 6x melee/3x ranged damage multipliers at Master (100).
Illusion: Grants Invisibility and Chameleon for permanent stealth.
Marksman: Boosts bow damage for ranged one-shots, complementing daggers.
Light Armor: Enhances mobility, reducing Fatigue drain.
Alchemy: Crafts Fortify Sneak and Damage Health poisons.
Security: Improves lockpicking for Thieves Guild quests.
Acrobatics: Boosts jump height and dodge rolls, aiding escapes.
This setup, inspired by Deltia’s Gaming, ensures rapid skill leveling while prioritizing stealth and one-shot potential.
Core Attributes and Skills
Agility: Governs Sneak accuracy, dagger hits, and Fatigue. Cap at 100 for precise strikes and dodge chance, per UESP.
Intelligence: Boosts Magicka for Invisibility casts. Aim for 80-100 by endgame.
Speed: Enhances movement for quick repositioning. Target 70-80.
Sneak: At 100 (Master), grants 6x melee/3x ranged critical multipliers, ignores 100% armor, and makes you undetectable while invisible. Level by sneaking near sleeping NPCs (0.3 experience per second), per IGN.
Illusion: At 100, enables permanent Invisibility via enchanted gear or spell stacking. Level by spamming Starlight (1 Magicka light spell) in Skingrad’s castle (0.3 experience per cast).
Marksman: At 100, adds knockdown chance on bow shots, ideal for ranged kills. Level by shooting summoned creatures (0.4 experience per hit).
Alchemy: At 100, crafts Grandmaster poisons (Damage Health + Silence). Level by making Restore Health potions (Wheat Grain + Apple, 0.4 experience per potion).
Achieving 100% Invisibility
Permanent invisibility is the build’s core, achieved via Illusion spells or enchantments, breaking detection, per elderscrolls.fandom.com. Options:
1. Illusion Spells (Legit)
Spell: Invisibility (Expert Illusion, 50 Magicka, 30 seconds, buy from Edgar Vautrine, Imperial City). At Illusion 100, craft a custom Invisibility spell (60 seconds) at Frostcrag Spire’s Spellmaking Altar (DLC).
Stacking: Cast Invisibility before the previous expires (every 55 seconds), maintaining uptime. With 400+ Magicka (Intelligence 100 + gear), cast indefinitely.
Leveling Illusion: Spam Starlight in Bruma’s chapel (300 casts to Expert), as per Deltia’s Gaming.
2. Chameleon Enchantments (Legit)
Source: Farm Transcendent Sigil Stones (level 17+, Oblivion Gates) for Chameleon +20% each, per UESP. Save before grabbing stones to reroll.
Gear: Enchant five items (Chest, Legs, Boots, Ring, Amulet) with +20% Chameleon, totaling 100%. At 100% Chameleon, you’re fully invisible without attacking, per GameRant. Use Mages Guild or Frostcrag Spire altars.
Example: Glass Armor set + Ring of Khajiiti (+10% Chameleon, Namira’s quest) + Amulet of Axes = 90-100% Chameleon.
3. Scroll Exploit (Optional)
Method: Use the Scroll Duplication glitch (unpatched in some versions, check your game, per Tech Drive Play). Equip 2+ Invisibility scrolls (buy from Anvil’s Mages Guild), drop an item (e.g., Apple), and rapidly select scrolls to duplicate. Cast 100+ scrolls for semi-permanent Invisibility, reapplying after attacks, per UESP.
Ethics: This exploit trivializes stealth, as noted by @FatalisReigns on X. For a legit run, stick to spells or Chameleon, achieving 100% invisibility by level 20.
One-Shot Mechanics: Daggers and Poisons
Weapon: Mehrunes Razor
Why: This Daedric dagger (Mehrunes Dagon’s quest, level 20+, 15 base damage) has a 1.98% chance to one-shot any enemy (except quest-essential NPCs), per UESP. Enchanted with Frost Damage +20 (Sigil Stone), it hits for 35+ damage, amplified by 6x Sneak multipliers.
How to Get: Complete “Pieces of the Past” (Dawnstar, or start via rumors). Save before the final chest for a better enchant.
Alternative: Ebony Dagger (base 12, enchant with Damage Health +20, buy from Imperial City’s Rindir’s Staffs) for early-game one-shots.
Poisons (Alchemy)
Recipe: At Alchemy 100, craft Damage Health + Silence + Paralyze poisons using Nightshade (Skingrad), Harrada (Oblivion Gates), Vampire Dust (Vilverin), and Bone Meal (dungeons). Deals 50+ damage over 10 seconds, silences mages, and paralyzes for 5 seconds, per GameRant.
Crafting: Use Grandmaster Apparatus (Skingrad’s All Things Alchemical) for +15 magnitude. Craft 50+ poisons at Cheydinhal’s guild hall.
Application: Apply to Mehrunes Razor before Sneak attacks, ensuring one-shots (6x * (35 + 50) = 510+ damage), per IGN.
Sneak Attack Formula:
Damage = Weapon Damage * Sneak Multiplier (6x) + Poison Damage.
Example: Mehrunes Razor (35) + Poison (50) = 85 * 6 = 510 damage, one-shotting most enemies (e.g., Bandits: 100-200 HP, Dremora: 300-400 HP).
Early-Game Strategy (Levels 1-5)
Escape the Imperial City sewers, grabbing the Blade of Woe (Dark Brotherhood initiation). Join the Mages Guild to buy Invisibility (Market District, Edgar Vautrine, 500 gold) and cast Shadow’s Invisibility for early stealth. Sneak near sleeping NPCs in the Bloated Float Inn (0.3 experience per second) to level Sneak to 25 (Apprentice). Craft Restore Health potions (Wheat Grain + Apple) at Bruma’s chapel to hit Alchemy 25, making Fortify Sneak +5 potions (Carrot + Bergamot Seeds). Equip Leather Armor (no encumbrance penalty) and enchant gloves with Fortify Sneak +5 (Mages Guild altar). Start the Dark Brotherhood via “A Knife in the Dark” (kill Rufio in Inn of Ill Omen), one-shotting with the Blade of Woe (6x * 10 = 60 damage). Prioritize Agility and Intelligence when leveling, sleeping in beds to confirm gains, as per Deltia’s Gaming.
Mid-Game Strategy (Levels 6-15)
With Sneak at Journeyman (50), you’re undetectable while sneaking slowly, and attacks ignore 50% armor, per UESP. Reach Illusion 50 (Expert) by spamming Starlight in Skingrad’s castle, casting Invisibility for dungeon runs like Vilverin. Farm Oblivion Gates (Kvatch quest) for Chameleon Sigil Stones (+15-20%), enchanting Glass Armor (buy from Bruma) for 60-80% Chameleon. Craft Damage Health + Silence poisons (Nightshade + Spiddal Stick) at Cheydinhal, applying to an Ebony Dagger (Rindir’s Staffs). Progress Dark Brotherhood quests (“Whodunit?” is perfect—sneak-kill guests undetected) and Thieves Guild (“Independent Thievery” for gold). One-shot enemies (6x * (12 + 30) = 252 damage), clearing dungeons like Sancre Tor. Train Acrobatics (jump on slopes, 0.3 experience per jump) for escapes, per Game8.
Late-Game Strategy (Levels 16+)
At Sneak 100 (Master), you’re nearly undetectable, and attacks ignore 100% armor, per UESP. Illusion 100 enables permanent Invisibility via Frostcrag Spire’s custom spells (60 seconds, 50 Magicka). Achieve 100% Chameleon with five +20% enchanted items (Glass Armor set, Ring of Khajiiti, Amulet of Axes), making you invisible without spells, per GameRant. Equip Mehrunes Razor (Mehrunes Dagon quest) with Grandmaster poisons (Nightshade + Harrada + Vampire Dust), dealing 510+ damage per Sneak attack. Complete the main quest by one-shotting Dremora in Oblivion Gates, bypassing combat with Invisibility. In Shivering Isles, sneak-kill Golden Saints (510 damage vs. 400 HP), and in Knights of the Nine, one-shot Aurorans. Dark Brotherhood’s “Honor Thy Mother” and Thieves Guild’s “The Ultimate Heist” are trivial—sneak past guards, kill instantly. Max Agility (100) and Intelligence (100), enchanting gear with Fortify Sneak +20 for overkill stealth, per Tech Drive Play.
Combat and Playstyle
Combat is simple: Sneak, apply poison, one-shot. Approach enemies crouched (Sneak mode, eye icon closed), ensuring no detection (100% Chameleon or Invisibility). Use Mehrunes Razor for its one-shot chance (1.98%, reroll with saves if needed). For ranged kills, use an Ebony Bow (base 14, enchant with Damage Health +20) with poisons for 3x * (14 + 50) = 192 damage, per IGN. If detected, recast Invisibility or sprint away (Acrobatics 100 for dodge rolls). Light Armor (100) adds 25% dodge chance, per GameRant, and Feather (Alteration) reduces encumbrance for faster movement. Avoid Expert difficulty, as tanky enemies (e.g., Dremora: 600+ HP) resist one-shots, per GamesRadar; Adept balances challenge and lethality.
Key Quests for the Build
Dark Brotherhood: “Whodunit?” and “Scheduled for Execution” are ideal for one-shots, sneaking past guards.
Thieves Guild: “The Ultimate Heist” and “Independent Thievery” leverage stealth for non-combat objectives.
Mages Guild: Access enchanting altars and Invisibility spells via “Joining the Mages Guild.”
Namira’s Shrine: Ring of Khajiiti (+10% Chameleon, east of Bruma) boosts early Chameleon.
Mehrunes Dagon’s Quest: Unlocks Mehrunes Razor, the build’s centerpiece.
Shivering Isles: Sneak-kill high-level enemies, testing your one-shot prowess.
Challenges and Workarounds
Detection Risk: Without 100% Chameleon, bright areas or close enemies detect you, per UESP. Use Night-Eye and dark corners, recasting Invisibility after attacks.
Magicka Limits: Early Invisibility drains Magicka (50 per cast). Stock Magicka potions (Flax Seeds + Steel-Blue Entoloma, Alchemy 25) or use Shadow’s daily cast, per IGN.
Quest-Essential NPCs: Some enemies (e.g., Martin) can’t be one-shot, requiring quest progression. Sneak past or use Invisibility, per Game8.
Enemy Scaling: High-level enemies on Expert difficulty have 600+ HP, resisting one-shots. Stick to Adept, as advised by Reddit’s u/Emotional-Pea9897.
Why This Build Shines
The Khajiit Thief with Shadow birthsign, 100% invisibility, and Mehrunes Razor delivers unmatched lethality, one-shotting enemies with 6x Sneak multipliers and poisons. Sneak 100 and Chameleon 100 ensure undetectability, while Illusion and Alchemy provide flexibility. Community feedback, like @OdaruKEKW’s clip of one-shotting an Oblivion Gate Dremora, proves its dominance, with u/SpeedyTamriel reporting a 2-hour main quest clear. Unlike Clair Obscur: Expedition 33’s Maelle, who needs Gommage for DPS, this build relies on stealth and precision, turning every strike into a death sentence. The remaster’s polished stealth mechanics and vibrant shadows enhance the experience, per VG247.
Final Tips
Save Before Strikes: Mehrunes Razor’s 1.98% one-shot chance may fail; reload for key kills, per Tech Drive Play.
Stock Poisons: Craft 100+ Grandmaster poisons at Cheydinhal for boss fights, ensuring 510+ damage.
Chameleon Priority: Farm Sigil Stones early (Kvatch gate) for 80-100% Chameleon, trivializing stealth, per GameRant.
Level Sneak Fast: Sneak near sleeping NPCs in the Imperial City’s Bloated Float Inn for 100 in hours, per Deltia’s Gaming.
Mod Option: “Stealth Overhaul” (Nexus, unverified for remaster) enhances detection, but this guide assumes vanilla play.
Conclusion: Rule the Shadows
The 100% Invisible Thief build in Oblivion Remastered transforms you into Cyrodiil’s deadliest phantom, one-shotting enemies from the shadows with Mehrunes Razor and Grandmaster poisons. With permanent invisibility via Chameleon or Illusion, Sneak 100 for 6x multipliers, and Khajiit agility, you decimate bandits, Dremora, and Daedric lords without breaking a sweat. As X clips of instant Arena kills and Reddit threads celebrate sub-3-hour speedruns, this build proves Oblivion’s stealth potential is unmatched. Enchant your gear, craft your poisons, and vanish into the dark—Tamriel won’t see you coming.
