Lucidity

The Lucidity is a craftable post-Moon Lord radiant weapon. At the cost of life, it rapidly shoots out crescent projectiles that home in on enemies, pierce infinitely and ricochet off of tiles infinitely. Each crescent lasts for about 4 seconds and inflict the Light Curse debuff for 2 seconds. When used, the ally with the least amount of health will receive life equivalent to half of the weapon's life cost.
