Arcane Bolt

An intricate, glowing circle of arcane or divine might is shaped into a sharp or blunt projectile such as a crossbow bolt or bullet, streaking forward at fantastic speed from your outstretched hand towards your target.  You fire a single projectile with a ranged spell attack versus the AC of the target.  On a hit, the projectile deals 2d8 force damage.  At higher levels, the projectile deals additional damage, or the spell can be shaped into alternate patterns (see description below).
