Reliquary
The Reliquary is a shrine that can be found in the basement of Abbey of St. Elspeth Citharede. It contains the Holy cithara.
If a player tries to take the cithara before the end of the quest, or without proper equipment (which means a specific combination of worn items, those that work are listed on the cithara's page), the player will be dealt exactly (current lifepoints - 1)
damage. (For example, if current LP = 990; you will be hit 989). In another case a message "An invisible force gently but firmly moves your hand away from the cithara" is displayed.
Taking the cithara for the first time results in 50,000 Prayer experience.
