Tomfoolery in Eberron
Harnesses the power of the moon. Each full moon it charges up power, which can be released to manipulate an object’s weight.
Moon pearl is a valuable material, like gold or platinum. At the start, its market value is 1 pp (100gp) per gram. Usually, it is found mixed in chunks of rock in very small concentrations of about 1 parts per thousand, so a 1kg rock might have only 1 gram of moon pearl.
When full charged, each gram can invert an objects weight for a short period of time. The time depends on the objects mass, for a normal 100-200 lbs creature, this equates to about 1 minute. Releasing this energy drains the moon pearl, which is then useless until it can be recharged at the next full moon.
