Soul gem detail

Soul gems are used to upgrade the Grotesque Armour. The gems can be obtained by trading in 500 Grotesque souls or directly won from Treasure Hunter. Each gem can be consumed to add 500 points to the armour along with 1,000 Slayer experience.

Any remaining soul gems were turned into 2,500 coins each on 29 February 2016.

They could also be obtained from Vic's Store in January and June 2017.
