Holy Arrow

Holy Arrows are available once Hardmode is engaged, and can be crafted from materials dropped by enemies in the surface Hallow. While lacking in direct brute power, they summon two falling stars to the point of impact. Each falling star does one-half the combined damage of the arrow and the bow used, and can additionally hit up to two enemies. Holy Arrows have a 1/6 chance to be recovered after impact.

The falling stars are similar to the Starfury's stars, and are the same type summoned by the Star Cloak. They also fall faster than the Starfury's stars. Terrain penetration stops once the stars have neared/crossed the height of the point of impact. Thereafter, they can be stopped by any solid block. The spawn point for the stars is relative to the point of impact in the same way that Starfury's effect is relative to the point where you click the mouse.

The starfall effect of these arrows makes them quite useful against bosses and other large enemies, and more specifically, The Destroyer. The stars not only deal extra damage against it, but also helps in controlling the number of Probes and other enemies that spawn.

They're still useful after Plantera/Golem Phase, since it can deal twice as much damage if all shots hit (Stars & Arrow), also excellent at killing the Martian Saucer, even on Expert mode.
