Wrath of the Ancients
The Wrath of the Ancients is a Hardmode spell tome that drops from Necromancers and Giant Cursed Skulls in the post-Plantera Dungeon. When used, it casts an energy pulse at the mouse cursor, which fires homing spirits at intervals for a significant amount of time. It is later used to craft The Dance of Light.
Its best modifier is Mythical.
