Hey im trying to get 153 for achievement diary ive looked at guides and ive done everything all quests needed ghost robes... the cleaning stuff downstairs and all quizes but im still on 148, what do i need to do? help please

Done the digsite portion yet? Found all the artifacts (I think that there are like 4 different artifacts)?

You can now get 158 kudos. Ghostly Robes is the quest mostly overlooked. The Varrock Beacon network quest, "Fired Up", was recently introduced, and it provides those 5 extra kudo points. I'd go back and talk to each curator on the three floors and see if they tell you there is still more to do.
