Vecna's curse

Vecna's curse refers to Vecna's predominant method of murder and torture. Using his supernatural psychokinetic abilities, Vecna can probe and influence the minds of others. Motivated by a cruel and misanthropic philosophy, Vecna targets particularly traumatized, mentally ill or insecure individuals.
Vecna gradually wears down his victims by inducing involuntary hallucinations, making them see apparitions such as a grandfather clock, black widow spiders and an otherworldly realm with red skies, as well as visions tailored to a victim's specific fears or history. After inflicting protracted suffering, Vecna finally executes the victim, using his powers to make them levitate before snapping their skeletons. Upon each execution, the psychic connection between Vecna and the victim is powerful enough to tear open a gate between Hawkins and the Upside Down, created in the exact location of the murder.
