Undine's Retribution

Undine's Retribution is a craftable Hardmode wand. It summons several aqua javelins from the ground that home in on enemies and inflict the Crush Depth debuff. The spears can also go through blocks, and will disappear after a moderate time if no enemy is hit. If no enemies are nearby, the spears will instead home in on the player.

Trivia

 * The weapon is a reference to Undines, which are female spirits or nymphs that inhabit water.
