Talisman
Talismans are a new type of amulets exclusive to the Talisman challenge. All Talismans are corrupted when they drop and thus cannot be crafted, but they have special implicits more powerful than ordinary amulets and can be normal, magic, rare, or unique just like other amulets.
Talismans will be encountered in the wild as a mob 'possessed' by a Talisman in a way that resembles possession by a Tormented Spirit, but unlike the spirits, which only possess rare and unique enemies and must be herded into doing it, Talismans can possess any level of enemy and will always start out possessing a mob. When the mob is killed, the Talisman drops as an item -- but if it is not picked up quickly by the player, it will attract another enemy and possess that enemy instead. Each type of Talisman grants the mob it possesses extra abilities (also much like a Tormented Spirit).
