Luminite Arrows are one of the strongest types of arrows. When fired, they are followed by a laser-like projectile after a short delay. The arrows and lasers have a fast travel time, and can pierce through three enemies, dissipating upon impact of the fourth. Luminite Arrows are destroyed upon use.
Both Luminite Arrows and their bolts reduce their damage by 4*1/25 (4%) each time they damage an enemy.
The bolts appear approximately 0.5 seconds after firing the arrows.
Secondary bolts will originate at the same position where the arrows were initially fired, regardless of player position or movement.
A secondary bolt will be spawned for each arrow that was initially fired. For instance, using a Tsunami, which fires five arrows at once, will cause five bolts to be released after the initial shot.
Unlike many other arrows, both Luminite Arrows and their bolts have a limited range. They will evaporate in the air if they exceed this maximum range.
A full stack of 999 Luminite Arrows can be crafted from just 3 Luminite Bars.
It can be difficult to hit a moving enemy with the secondary bolts. Enemies can be damaged by both the arrows and their bolts if they are on a long, flat surface (e.g. a skybridge).
Luminite Arrows synergize exceptionally with the Phantasm bow:
The Phantasm releases four arrows (and thus four secondary lasers) while consuming only one arrow from the inventory.
It has a 66% chance not to consume arrows, which is very desirable considering the value of Luminite as well as its ineligibility for recovery.
A successful hit with Phantasm can allow for a triple hit on an enemy: first the initial shots, then the Phantasm's secondary arrow projectiles, and lastly the bolts from Luminite Arrows.
With the appropriate setup and proper movement, a Phantasm with Luminite Arrows may trivialize even the Moon Lord.
The quote "'Shooting them down at the speed of sound!'" may be a reference to the line "Rolling around at the speed of sound" in the song "Escape from the City" from the 2001 platform game Sonic Adventure 2.
