John Simon Ritchie's Padlock Necklace

Origin
John Simon Ritchie, known by his stage name Sid Vicious, was the bass player for the Sex Pistols. However his constant drug use made him unreliable in the band, as he was hospitalized during the recording of the band’s only studio album. It was during this time with them that he met manager and future girlfriend Nancy Spurgeon, who worsened his addiction. Sid later woke up in a hotel one morning to find Nancy dead from a stab wound. He was arrested and released but a short time later re-arrested for assault and sent to prison drug rehab. After his release, his mother threw him a party where she gave him heroin; he died in his sleep from an overdose.

Effects
This padlock was imbued by the mystery and scandal surrounding the death of Nancy Spungen. The necklace induces a drug stupor that is said to be similar to the high heroin creates. While in this state, the person will seek out a loved one who the user says "Treats them like sh*t" and murder them with any available object to do so. 105 days later, the same number of days between Nancy and Sids' deaths, the user will die from the artifact's effects in the form of a drug overdose.
