Ogre coffin

Ogre Coffins are coffins located in the level one basement of Jiggig and just outside Jiggig directly south. The coffins can be opened by either of two means:

Picking the lock requires level 20 Thieving, yielding 27 experience. Failing to pick the lock yields 1 thieving experience and lowers your Thieving stat temporarily.
Opening the coffin using an Ogre coffin key. Keys are obtained from drops by Zogres and Skogres in Jiggig, or through gambling in Soul Wars.

Picking the coffin lock[]

You attempt to pick the lock on the coffin:

You unlock the coffin... (the dialogue tells you the items found, if any).
Your lockpick snaps (if you have one; a lockpick not required to pick the locks).
You fail to pick the lock - your fingers get numb from fumbling with the lock.
Outside Jiggig only: You fail to pick the lock - your fingers get numb from fumbling with the lock (and you get caught).

Ogre Guard: Hey thief! I's gonna teach ya!

You're knocked unconscious and dropped down a chute.

You slowly wake up in a strange place (you are in the level one basement of Jiggig).

The locks cannot be picked whilst in combat; attempting to do so will display the message, "You're in mortal danger, thieving is the last thing on your mind."

Each time you fail and your fingers get numb, your Thieving level will be temporarily drained by 1-4 levels. Note that this drain will stack with itself, and if your Thieving level drops below 20, you will no longer be able to pick the lock. Failure is frequent even at level 99 Thieving, so expect a significant drain. Lowered Thieving levels can be restored by drinking Super restore potions or via other means such as the Bloated leech and Blood Drain scrolls.

Bones[]

The bones found in the Coffins give a very large amount of Prayer XP. These can be especially useful when used on a Gilded altar or taken to the Ectofuntus for the extra prayer bonus.

The chances are calculated using a sample size of 2560.

Bones	Prayer XP	Price	Chance
Zogre bones	22.5	1,401	49.96%
Fayrg bones	84	8,488	10.86%
Raurg bones	96	33,145	7.66%
Ourg bones	140	27,878	3.75%

This means that the average profit for looting 100 coffins using keys would result in 274,807 coins profit, ignoring the other rewards, since they are either untradeable or very cheap. Do note, however, that the expensive Raurg bones are almost exclusively used for Daily Challenges, and as such have a very low demand, making them unlikely to sell at or near the Grand Exchange guide price for a very long time.
