Rainbow Rod

The Rainbow Rod is a magic weapon that launches a controllable missile, similar to the Flamelash or Magic Missile. The missile is white and emits light that rotates through the color spectrum, creating a rainbow effect underground or at night. With the proper equipment, the Rainbow Rod becomes one of the most damaging weapons in the game, and is useful in boss fights against enemies with high defense. It is relatively slow firing compared to other top-end weapons. You can also use it as a light if you are exploring caves, by clicking where you want it to light up. It also makes a large flash of light when it hits anything, much larger than Flamelash, so you can search walls for caves and ore. While you are still holding the mouse, controlling the rainbow, your mana will not regenerate. The rainbow rod is unique in the fact that out of the three "magic missile" type weapons, (the other two being Flamelash and Magic Missile) it is the only one that can be crafted. It has the strongest base damage of all weapons. When reforged with the Mythical prefix, wearing full Hallowed armor with the headgear, and with the Magic Power, Clairvoyance buff and a Sorcerer Emblem, it deals 94 damage per shot and costs 7 mana, 1 less than a regular Laser Rifle. Adding a Mana Regeneration buff makes it super effective, as your mana will regenerate to full in less than ten seconds.
