Prismatic Hat
This flat cap has seven colors, mixing in stripes and interwoven patterns. Each color can be "grabbed" by the wearer and pulled out fo the cap to be thrown at someone causing a different effect depending on the color. The thrown effect looks like a hat flying out to hit the person (or placed wherever) and has the range and aerodynamics associated with a real hat. Once all colors are used it appears to be a normal grey hat and must be exposed to a naturally occurring rainbow to recharge.
Red - A red beret flies out, causing the target struck to become enraged with their own hat, helmet, head covering or wig, although real hair is not effected. The affected individual will pull off their hat, throw it on the ground, and stomp on it, while remaining angry at it for several hours to the point of not picking it up or wearing it.
Orange - A orange beanie flies out, causing the target struck to grow huge amounts of bright orange hair from their head. The effect will quickly swamp the nearby area in hair, although it will not crush or suffocate the target or those nearby. The hair is real and permanent until cut off.
Yellow - This color produces a yellow hard hat which must be affixed to another persons head not currently covered by a hat. Once on the head it will provide complete protection from all forms of attack or damage to the head from anything up to and including an outer god. The effect lasts for 15 minutes, provides no protection to the rest of the body, must continue to be worn on the head to function and can not be used on the prismatic hat wearer themselves.
Green - This green Kepi is placed on any inanimate object, including most plants. The object is brought to life and will move and take orders from the person who placed the hat on. It has the intelligence and combat skills of an average soldier with combat forms appropriate to however it is shaped. The effect lasts until sundown or sixty seven minutes, whichever is shorter.
Blue - A blue garden or picture hat which is thrown and hits a target. This inflicts terrible brain freeze until the target eats a warm, hot or spicy food. While not deadly it is quite debilitating, even to things which normally can not experience pain or do not have a brain... somehow.
Indigo - When placed on the ground this blue top hat projects an image of Isaac Asimov who will analyze the science and history of the world around him and explain it to those viewing. Any effects not at least partially grounded in science will fail within 325 meters, but not to the point that anyone will be immediately harmed by life support or movement effects stopping at inopportune times. He can hear what is going on around him and is more then willing to debate or converse about what is going on. The top hat itself is firmly rooted in hard science, no I am not going to explain but you can ask the projection if you want. The effect lasts for 15 minutes.
Violet - A violet trucker hat thrown at a target who becomes non-violent immediately to anything around them. They will be willing to talk out any problems (if able) and will hold to any reasonable agreements made. If attacked while under the effect the target gains supernatural strength, durability and powers (if capable of normal magic/psionics/powers) and will gleefully destroy whoever attacked them while still being peaceful to everyone else and even holding conversations. The effect lasts until dawn or 93 hours, whichever is shorter.
