Updated today, I just changed some sentences in the guide as most of theme were still correct:

 

Restless ghost

They added a icon on everything that has to do with the quest

 

# You can find the skull at the mining spot on the coast south of lumbridge, search the rocks east of the mining spot and you will get attacked by a level 13 skeleton warlock that you can either fight or just run from.

 

Reward:

thanks, you've been credited +guides edited+items added :)

You can get the ancient bones (5) when you have done this quest previously. Did this quest many years ago.

 

It's the same thing in the few f2p quest, there is extra reward added that "older" players can get by talking to quest related person again. In quest list, on the quest notes, there is a text for more rewards.
