The Ark of the Ancients is a craftable Hardmode broadsword that auto-swings. It fires either a large or a small sword beam projectile along with two stars that fall from the sky at the cursor's position. The large projectile penetrates enemies and inflicts the Elemental Mix debuff for 2 seconds. The small projectile is identical to the Enchanted Sword projectile. The stars deal 50% of the weapon's damage. Enemies are inflicted with the Holy Flames debuff for 5 seconds upon direct weapon hits.
Its best modifier is Legendary.
