The short version
30-second read- Protect from Missiles only halves his ranged hits. His ranged max is 26 and half still gets through, so eat early.
- Snare him and cast between binds. That needs 50 Magic and 40 Prayer, and members can use Entangle or Ice spells for a firmer hold.
- Fight melee with a wall behind you. His slam knocks you back, and a wall stops the push, though your next attack is still delayed.
- The hill giant club drops at 1/118. It only comes from his chest, needs 40 Attack and has +65 crush and +70 Strength.
Obor and Giant Keys at a Glance
Giant keys drop from hill giants at 1/128, doubled to 1/64 for hill giants in the Wilderness. Obor drops them at 1/16 and his chest can roll another at 1/16. Since the 25 June 2025 update a key is only needed once, to unlock his gate. After that you can fight him as often as you like and use one key on his chest per kill.
Obor is a level 106 free-to-play hill giant boss with 120 hitpoints, behind the locked gates on the western wall of the hill giant area in Edgeville Dungeon. He hits with melee (crush, max 22) and ranged (max 26). His chest is the only source of the hill giant club (1/118), a 40 Attack two-hander and the best crush weapon in free-to-play.
Prayer does not make you immune here. Protect from Missiles halves his ranged damage instead of blocking it, and his melee slam can knock you back.

How to Get Giant Keys
There is no quest or skill requirement. The only gate is one giant key, used on the gates to his lair the first time. That first unlock does not use the key; keys are spent on his chest after each kill. They are stackable and untradeable.
| Source | Drop rate | Notes |
|---|---|---|
| Hill giants | 1/128 | The ones in Edgeville Dungeon stand right next to Obor's gate |
| Hill giants in the Wilderness | 1/64 | Double rate, with PK risk |
| Obor | 1/16 | Raised from 1/32 on 2 July 2025 |
| Obor's chest | 1/16 | Rolled when you open the chest with a key |
Get the first key from hill giants, then let Obor supply the rest. The wiki puts fast members' kills with a giantsoul amulet, a desert amulet 4 and burning claws at 120+ an hour, which comes to roughly 8 keys an hour.
Where Obor Is and How to Get There
Obor's lair is behind the locked gates on the western wall of the hill giant area in Edgeville Dungeon.
Enter Edgeville Dungeon, run to the hill giants and use a giant key on the gates; after the first time they open without one. You arrive in a safe zone and climb down the rocks to fight him. A charged giantsoul amulet teleports you right outside the lair.
Recommended Combat Stats and Gear
| Check | Value |
|---|---|
| Prayers for its own attacks | Protect from Missiles (halves his ranged hits); Protect from Melee if you fight up close |
| Its Defence level | 60 |
| Its Magic level | 1 |
| Its lowest defence bonus, per its infobox | light ammunition, standard ammunition, heavy ammunition, magic |
| Elemental weakness | 20% to earth spells |
The wiki's suggestions: free-to-play rangers want 60 Ranged, 50 Defence and 40 Prayer in a rune chainbody, and members with 75 Ranged should bring a toxic blowpipe. With 50 Magic and 40 Prayer you can Snare him and cast between binds. Melee is faster but riskier and wants 50 Attack, Strength and Defence.
Inventory and Supplies
- Food for his 22 melee and 26 ranged max hits. Protect from Missiles only halves the ranged ones.

Where Obor Sits in Progression
In our index Obor is a difficulty 1 of 5 beginner boss, alongside Bryophyta and Scurrius. The usual next step up is Sarachnis.
Fight Strategy
- 1
Turn on Protect from Missiles before you climb down the rocks.
- 2
Mage or range from a distance.
Snare him and recast as soon as he can walk again; members can use Entangle or the Ice spells, since Snare does not always hold him for its full duration.
- 3
In melee, expect his slam to knock you back.
A wall behind you stops the push, but your next attack is still delayed.
- 4
Eat early.
With his ranged hits only halved, damage still gets through your prayer.
- 5
After the kill, open the chest with a key.
Trying the chest also makes him respawn shortly after, key or not.
Drops and What Obor Is Worth
His own drop is a hill-giant-style table: giant bones on members' worlds (buried straight from the floor), iron gear, small runes, herbs and seeds, an ensouled giant head at 1/25 and the 1/16 giant key. The chest holds the better loot: a guaranteed beginner clue, another giant key at 1/16, and the hill giant club at 1/118.
The club has +65 crush and +70 Strength, close to a rune 2h sword with the slash and crush bonuses swapped. It is a free-to-play PvP favourite and can also cut spider webs.
Combat Achievements
Obor has six Combat Achievement tasks, worth 9 points in total:
- Obor Novice (easy): open his chest once.
- Sleeping Giant (easy): kill him while he is immobilized.
- Fighting as Intended (easy): kill him on a free-to-play world.
- Back to the Wall (medium): kill him without being pushed back more than one square by his knockback attack.
- Obor Champion (medium): open his chest 5 times.
- Squashing the Giant (medium): kill him without taking any damage off prayer.
The Snare method fits Sleeping Giant: land the killing hit while he is bound. For Back to the Wall, fight with a wall behind you so the slam cannot push you. Champion needs five giant keys, since only a chest opening counts.
Ironman Notes
He counts toward a hill giant Slayer task from Mazchna or Vannaka, at 129 Slayer XP a kill.
For ironmen and free-to-play accounts the chest is a steady source of beginner clues, since one is guaranteed every time you open it.
Common Mistakes and Death Causes
- Expecting Protect from Missiles to block his ranged hits. It only halves them.
- Thinking every fight costs a key. Since June 2025 the key only goes into the chest.
- Letting a Snare run out and getting caught in melee range.
- Climbing down the rocks before prayer is on.
- Fighting in melee with too little food for the knockback and the ranged chip damage.
FAQ
How do I get a giant key in OSRS?
Kill hill giants: 1/128 normally, 1/64 in the Wilderness. The hill giants in Edgeville Dungeon are right next to Obor's gate. Once you are in, Obor drops keys at 1/16 and his chest gives them at 1/16.
Do I need a giant key to fight Obor?
Only once. The first key unlocks his gate for good and is not used up. After that you only spend a key to open his chest after a kill.
Where do I use a giant key?
On the gates in the western wall of the hill giant area in Edgeville Dungeon the first time, then on the chest in Obor's lair after each kill.
Which protection prayer should I use at Obor?
Protect from Missiles. It halves his ranged damage rather than blocking it, so keep eating, and keep him bound with Snare so he cannot reach melee range.
How hard does Obor hit?
22 with melee and 26 with ranged. He has 120 hitpoints.
Where is Obor?
In his lair behind the gates on the western wall of the hill giant area in Edgeville Dungeon. A giantsoul amulet teleports you to the entrance.
Is Obor worth doing?
For beginner clues, giant keys and a shot at the hill giant club, yes, especially on a free-to-play account. The club is his only unique and comes from the chest at 1/118.
What kills people at Obor?
Standing in melee range with low food. His 26 ranged max is only halved by prayer and the slam pushes you around, so most deaths come from slow chip damage with too little food.

Bottom Line
Get one giant key from the Edgeville hill giants, unlock the gate, and Obor supplies most of his own keys after that. Pray Missiles, keep eating, and keep him snared or at range.
Bryophyta works the same way with mossy keys in the Varrock Sewers. If Obor is blocking a Combat Achievement or an unlock you actually want, our PvM service is done by hand. Otherwise the bosses list has the full index.
