"Giant boss" redirects here. For the moss giant boss, see Bryophyta.

Obor, the Hill Titan, is the hill giant boss residing in his lair, located in the locked gates found at the western wall of the hill giant area in the Edgeville Dungeon.

In order to access Obor's Lair, the player must obtain a giant key from a Hill Giant or Cyclops. Each giant key permits for only one attempt, similar to Skotizo and dark totems.

When the player first enters Obor's Lair, they will be in a safe zone, where they must climb down the rocks in order to fight him. Obor attacks with Melee and Ranged, and can detect whether the player is using protection prayers against his current attack style. For example, he will use ranging attacks if Protect from Melee is used.

Warning: If you die within the lair, there is absolutely no way for you to retrieve items lost on death!


A player fighting Obor, the Hill Titan.

An easy strategy for lower-level players (with 50 Magic icon.pngMagic and 40 Prayer icon.pngPrayer) is to always turn on the Protect from Missiles prayer BEFORE climbing down, and then using Snare to prevent Obor from reaching you. Cast Snare every time Obor is able to walk again. Use Magic to kill him, since your magic armour's bonuses will also increase your chances of a successful Snare cast. Even with this strategy, however, bring enough food, as Obor can do serious damage as soon as the Snare wears off.

Non-members can attempt the same strategy using Bind, but since that only immobilises Obor for half the amount of time, it will be much harder to do this successfully. However, if you bind him, run away, cast two Blast spells and repeat, you should still have a good chance with Protect from Missiles activated.

It can be useful to know that Obor does not always keep walking up to melee distance before attacking, but never attacks when unable to move. This means he might stop walking towards you before standing next to you, giving you the time to snare or bind him without having to run to the other side of the arena. This makes it easier to cast more spells in a shorter amount of time, making the fight more efficient.
