Frigidflash Bolt

The Frigidflash Bolt is a craftable Hardmode spell tome that is an upgrade of both Frost Bolt and Flare Bolt. It fires a slow-moving ball of flash-freezing magma that can be autofired. The projectile travels in a straight line, emits a bit of light, is unaffected by gravity, can pierce through 4 enemies and can bounce off 4 walls. It inflicts the On Fire! and the Frostburn debuff on hit enemies.
