Tachyon Arrow

A Tachyon Arrow is an intricate Necron wrist-mounted energy caster worn by members of Necron royalty, such as Necron Overlords, Necron Lords and Necron Destroyer Lords. When activated, it transmutes a sliver of inert metal into an unstoppable thunderbolt capable of piercing the heart of a mountain. Such a weapon has near infinite range, and is able to penetrate almost any form of armour, including that of Titans. However, it can only be used once, before the guardians of a Necron tomb must tend to its technologies.
