The memoriam crystal (unknown) is a memoriam crystal found within Prifddinas. It is found in the Meilyr Clan district near the bank chest behind a harmony pillar. It can only be obtained while equipping a Clan Crwys cape and having three cooking apples and three chocolate bars in the player's inventory. Equipping a Clan Crwys cape is required, a master clan cape will not work. Using this crystal on the memoriam device found in the Tower of Voices will cause it to turn into the Shattered memoriam crystal. This also unlocks [Name] the Troublesome title.
