# Enfeebling Arrow *Source: Xanathar's Guide to Everything p. 29* You weave necromantic magic into your arrow. The creature hit by the arrow takes an extra `dice:2d6|noform|noparens|avg` (`2d6`) necrotic damage. The target must also succeed on a Constitution saving throw, or the damage dealt by its weapon attacks is halved until the start of your next turn. The necrotic damage increases to `dice:4d6|noform|noparens|avg` (`4d6`) when you reach 18th level in this class.
