Rainbow Rod

The Rainbow Rod is a Hardmode magic weapon that launches a mouse-controllable projectile, similar to the Flamelash or Magic Missile. The projectile is white, and emits a good deal of light that rotates through the entire color spectrum (when a color Lighting Mode is selected). Unlike the Flamelash, the Rainbow Rod's projectile can move through Water without dying, as well as Lava. It can be controlled for up to one minute before dissipating.

Tips

 * With the proper equipment, the Rainbow Rod was one of the most deadly weapons before 1.2, with up to 124 damage possible, making it extremely useful in boss fights and against other enemies with high defense.
 * The Rainbow Rod can also be used to light areas remotely.
