Grotesque soul

Grotesque souls are a Treasure Hunter prize that can be used to unlock Grotesque Armour. 10,000 souls may be released every day to give up to 50,000 experience in Prayer or Slayer (depending on your skill level). 50 souls can be obtained by killing any monster once every 10 minutes. 100 souls will be rewarded if the monster is from a Slayer task.

After initial release on 27 January 2016, players were able to sell Grotesque souls for 2,100 coins each to any general store in RuneScape. Several hours later a patch was rolled out which rendered the souls unsaleable.
