OSRS Kill Obor While Immobilized Guide for Combat Achievement

Defeating Obor, the Hill Titan, in Old School RuneScape (OSRS) is a thrilling challenge, especially for free-to-play (F2P) players and members aiming to complete the “Sleeping Giant” Combat Achievement. This achievement requires you to kill Obor while he is immobilized, adding a layer of strategy to the fight. In this comprehensive guide, we’ll walk you through everything you need to know to successfully complete this task, including preparation, strategies, gear setups, and tips to avoid common pitfalls. Whether you’re a low-level player or a seasoned adventurer, this guide will help you conquer Obor efficiently.

Obor is a level 106 Hill Giant boss located in his lair within the Edgeville Dungeon. Accessible to both F2P and members, he’s a popular target for players seeking valuable drops like the Hill Giant Club and rune kiteshield. The “Sleeping Giant” Combat Achievement, categorized as an easy task, requires you to defeat Obor while he’s immobilized using spells like Bind, Snare, Entangle, or freeze spells such as Ice Barrage. This guide focuses on achieving this goal with minimal hassle.

Why Immobilize Obor?

Immobilizing Obor prevents him from closing the distance to use his powerful melee attacks, which can hit up to 22 damage. His ranged attacks, while still dangerous (max hit of 28), are reduced by 50% when using Protect from Missiles prayer, making magic-based strategies safer and more effective for this achievement.

Key Requirements for the Fight

• Giant Key: Dropped by Hill Giants (1/128 rate) or Cyclops, required to enter Obor’s lair.
• Magic Level: At least 50 for Snare (F2P) or higher for Entangle/Ice spells (members).
• Prayer Level: 40 for Protect from Missiles.
• Combat Stats: Recommended 50+ Magic, 50+ Defence, and 42+ in other combat stats for F2P; 60+ for members.

Preparation for the Fight

Proper preparation is crucial to successfully kill Obor while he’s immobilized. This section covers gear, inventory, and how to reach his lair efficiently.

Recommended Gear Setup

Your gear should prioritize magic attack bonuses to ensure successful immobilization spells and decent defence to survive stray hits. Below is a table outlining recommended gear for F2P and members:

Slot	F2P Setup	Members Setup
Head	Wizard hat	Void mage helm or Ahrim’s hood
Cape	God cape	Imbued god cape
Body	Wizard robe	Void robe top or Ahrim’s robetop
Legs	Zamorak monk bottom	Void robe bottom or Ahrim’s robeskirt
Weapon	Staff of fire	Trident of the swamp
Shield	Book of darkness	Arcane spirit shield
Gloves	Leather gloves	Void gloves or Barrows gloves
Boots	Leather boots	Eternal boots
Amulet	Amulet of magic	Occult necklace

Note: For members, Void Knight or Elite Void equipment with the mage helm boosts magic damage and accuracy, making it ideal.

Inventory Setup

Your inventory should include runes for immobilization and attack spells, food, and emergency teleports. Here’s a suggested setup:

• Runes: Nature and water runes for Snare (F2P); add earth runes for Entangle or chaos/death runes for Ice spells (members).
• Attack Spells: Fire Blast runes (F2P) or Trident charges (members).
• Food: 10-15 lobsters or swordfish (F2P); sharks or better (members).
• Prayer Potions: 2-4 for maintaining Protect from Missiles.
• Teleport: Amulet of glory or Edgeville teleport for quick escape.

Getting to Obor’s Lair

Obor’s lair is behind locked gates in the hill giant area of the Edgeville Dungeon. Use an Amulet of Glory to teleport to Edgeville, then head south to the trapdoor near the bank. Descend and navigate to the western wall. Members can use the giantsoul amulet to teleport directly outside the lair.

Strategies to Kill Obor While Immobilized

The key to completing the “Sleeping Giant” achievement is to immobilize Obor before dealing the final blow. Magic is the most reliable method due to Obor’s weakness to magic attacks and the availability of immobilization spells.

F2P Magic Strategy

For F2P players, the strategy revolves around using Snare (level 50 Magic) to immobilize Obor and Fire Blast for damage:

1. Activate Protect from Missiles before climbing down the rocks to enter the lair. Obor attacks immediately upon entry.
2. Cast Snare as soon as you see Obor to prevent him from reaching melee range.
3. Run to the opposite side of the lair (west or east wall) to maximize distance.
4. Attack with Fire Blast twice per Snare cycle, as Obor may stop short of melee range, giving you time to cast.
5. Recast Snare every 9.6 seconds (16 ticks) or when Obor starts moving again. Note that Snare may not always hold for the full duration, so stay alert.
6. Deal the final hit while Obor is snared to complete the achievement. Ensure he’s at low HP (10-20) before casting Snare for the killing blow.

Tip: If Obor’s slam attack stuns you against a wall, spam-click to move immediately to avoid being stuck. Bring enough food to tank occasional hits.

Members Magic Strategy

Members have access to stronger immobilization spells like Entangle (level 79 Magic) or Ice spells (e.g., Ice Barrage, level 94 Magic), making the fight easier:

1. Enable Protect from Missiles before entering the lair.
2. Cast Entangle or Ice Barrage to immobilize Obor. Entangle lasts 14.4 seconds, while Ice Barrage can freeze for up to 19.2 seconds.
3. Use high-damage spells like Fire Wave or Trident of the Swamp, which also poisons Obor for extra damage.
4. Monitor HP and cast your immobilization spell when Obor’s HP is low (10-20) to ensure the final hit lands while he’s immobilized.

Note: The Zamorak godsword’s special attack does not count for this achievement, so stick to magic-based immobilization.

Non-Magic Immobilization (Advanced)

Some players, particularly pures or those with restricted accounts, may want to avoid magic. However, non-magic immobilization options are limited and not recommended for most players:

• Blackjacking: There’s a chance to stun Obor with a blackjack, but this is unreliable and unconfirmed for the achievement.
• Boosted Bind: Using Last Man Standing rewards to temporarily boost Magic for Bind is theoretically possible but impractical due to the 12-second kill window.

For most players, magic remains the safest and most consistent method.

Common Pitfalls and How to Avoid Them

Many players struggle with the “Sleeping Giant” achievement due to bugs or misunderstandings. Here are common issues and solutions:

Buggy Achievement Tracking

Reddit users have reported the achievement not registering despite immobilizing Obor. This may be due to killing Obor too quickly after immobilization or the spell wearing off before the final hit. To avoid this:

• Wait a tick after casting your immobilization spell before dealing the final blow.
• Use a stronger spell like Ice Barrage to ensure a longer immobilization window.
• Lower Obor’s HP first, then immobilize and kill in one hit to guarantee the condition is met.

Taking Too Much Damage

Obor’s attacks can be punishing if you’re not prepared. Mitigate damage by:

• Always activating Protect from Missiles before entering.
• Keeping your distance to avoid melee hits.
• Eating proactively when your HP drops below 50%.

Rewards and Benefits
