Scrimshaw of corruption detail

The scrimshaw of corruption is a pocket slot item. It is obtained in inactive form from the loot crates awarded upon killing the Giant Mimic, or from the Motherlode Maw, by combining a scrimshaw of aggression and a scrimshaw of sacrifice.

While active, this item will combine the effects of both the scrimshaw of aggression and the scrimshaw of sacrifice: It will cause one random monster around the player to become aggressive (when not already in combat) and will give 50% extra combat experience when killing monsters, in addition to 50% extra Slayer experience when killing monsters on a slayer assignment. In exchange for this bonus, no drops are received, with the exception of secondary drops such as charms, Spirit gems and ferocious rings.

The experience from this scrimshaw is not directly affected by bonus experience; however, bonus experience will be earned in addition to the bonus experience from the scrimshaw.

Each scrimshaw of corruption will last for one hour of activation before crumbling to dust. The scrimshaw can be upgraded to a superior version that lasts for 4 hours using 10 ancient bones at the Scrimshaw Crafter, once the ability to do so is purchased from the Elite Dungeon Reward Shop for 250,000 Dungeoneering tokens.

Like all scrimshaw, partially used scrimshaw of sacrifice can be combined to sum the time remaining (to a maximum of 1 hour per scrimshaw).

The inactive scrimshaw can be split at any time to make a scrimshaw of aggression (inactive) and a scrimshaw of sacrifice (inactive).

The item was originally obtainable for a limited time from Treasure Hunter during the corrupted chests promotion. It was later made available again from 18 February 2016 to 22 February 2016 during 'The Mimic Rises' Treasure Hunter promotion, as a potential reward from large and huge loot crates. It was then available a third time from 17 November 2016 to 21 November during 'The Revenge of the Giant Mimic' promotion. On 4 September 2017, the scrimshaw was also made obtainable from the Motherlode Maw, and availability was further extended as a reward from Giant Mimic when the boss returned permanently on 5 February 2018.
