One of the brothers in the monastery has taken note just how many corpses are lying at the wilderness and suggests to do something about it. The brother isn't one of the bravest and asks you to collect bones in the wilderness and bring them back to OSRS gold him so he could release the anguished soul.

Now I know their are many bones in the wilderness but you cant collect any old bones the bones you need to collect have a colored haze about them depending how hard they'll be to release the tougher they are to release the more experience they hand down to you. Blue is your least experience purple is a medium quantity red is a great deal and flames burning around these are the hardest. To free the spirits you need to know what's keeping them from departing, bring them into the brother to have him do a reading on them.

The bones//spirit will request you to do a random task to these, the actions can vary from slaying the beast that ruined it, giving a NPC a message, coating them with a food they used to love, dyeing with them in the place you found it (The ribs may entice one to the spot once your round the general region ), since you can see they are random jobs and aren't confined to what I've recorded.

The tougher bones may ask jobs which are beyond you such as slaying the Kalphite queen 3 times, if you can perform the task at your current level in Runescape the brother will maintain the bones/soul for you till you can. If you damage a monster that the bones do not require you to buy RuneScape gold damage it'll disappear from your inventory in a puff of smoke.
