Torment is a miscellaneous item that is automatically obtained randomly when killing Wandering Spirit. Don't be fooled by its 'charm' label as it is actually a curse.
Effect: It decreases 50% of its victim's ATK and MATK, and decreases ASPD by 10 points.
Restriction: It is character bound and cannot be deleted.
Cure: The only way to get rid of it is to keep your character logged in for a total of 2 hours (doesn't have to be consecutive), or use Mitridatium.
