Atlantis

The Atlantis is a Hardmode wand which is dropped by the Leviathan and Anahita. It shoots halberds which pierce and travel through walls, in a distinct pattern consisting of one halberd in a straight line, then two halberd connected in the shape of a V, heading outwards from the player in a straight line.

Trivia

 * The name "Atlantis" originates from a fictional island of the same name from dialogues written by the Athenian philosopher, Plato.
 * This weapon appears to be a halberd, the same type of weapon that Anahita wields.
 * This weapon previously resembled a Trident, and before that, a spell tome.
