Edmund Musgrave Barttelot's Cane

Origin
Edmund Musgrave Barttelot (28 March 1859 – 19 July 1888) was a British Army officer, who became notorious after his allegedly brutal and deranged behavior during his disastrous command of the rear column left in the Congo during H. M. Stanley's Emin Pasha Relief Expedition. He has often been identified as one of the sources for the character of Kurtz in Joseph Conrad's novel Heart of Darkness.

His abusive behavior included repeatedly beating the African porters until fatally wounded, stabbing others with a steel-tipped cane and believing his fellow officers were traitors. When Barttelot tried to interfere with a native festival, he was shot dead by one of the villagers.

Effects
The user will feel the insatiable urge to beat and wound any person near them. They will only stop when they feel they have done the appropriate amount of damage to that person and will move on to the next. The effects are amplified when wielding the cane, turning the user into a frenzied monstrosity. Contact with the tip will cause large amounts of bleeding and tissue damage, uneven breathing and an extreme sensitivity to light and sound.
