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. When reforged with the Ruthless prefix, wearing a [Mythril Hood], an Adamantite Breastplate, and Hallowed Greaves and with the Magic Power, Clairvoyance, and Well Fed buffs, and a menacing Sorcerer Emblem and four other menacing accessories, it deals 124 damage per shot and costs 9 mana, 1 more 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. Also, with these upgrades, it is the most powerful weapon in the game, being able to defeat a player with maximum defense in two hits.
