Mourningstar

The Mourningstar is a craftable post-Moon Lord flail and is the direct upgrade of the Solar Eruption. Similarly to the Solar Eruption, the Mourningstar fires two solar spear-like projectiles that extend and retract from the player's position, following a narrow arc in the general area of the cursor for the duration of their travel. The flails have infinite piercing capabilities, ignore tiles, and create explosions when hitting enemies. Both the flails and the explosions created inflict the Daybroken debuff on hit enemies.

Trivia

 * Mourningstar's name is a pun on the term "Morning Star", a name given to certain pre-sunrise sky objects or to a type of spiked mace, and the word "mourning", which means to grieve over someone's death.
 * It shares the "morning" and "mourning" pun with Mourning Wood.
