TF2 All Cosmetic Spells Showcase (Halloween Effects)
Halloween Spells are used to give various Halloween-themed effects to weapons, cosmetic items, or classes, depending on the spell. They were enabled and obtainable annually during subsequent Halloween events, prior to Scream Fortress 2015.
They could be found during Halloween events inside of Haunted Halloween Gifts on Ghost Fort, or from a Pile of Curses.
Scream Fortress 2014 would be the last Scream Fortress update to allow players to gather Halloween spells. Since Scream Fortress 2015, Halloween spells are not acquirable, as Haunted Halloween Gifts were replaced with the Soul Gargoyle, which do not distribute spells.
The only way to obtain an spelled item is to acquire an item that had the spell inserted before 2015.
The effects of Halloween spells are visible only during Halloween events(from October 1st to November 7–14), Full Moons, or on servers under the effects of the Enchantment: Eternaween tool item.
