This is a special weapon for Monks. It has such a high price because this is more of a drop type weapon, or a quest completion reward. It is a legendary weapon. It can be a gift of the Gods to special Monks, such as a divine favor from a Monk's Deity, or a reward for a completion of Secret quest for the Monk. This weapon is generally a divine mythrilweave material, but there can be mimicry fists made by master craftsmen of from lesser materials. Lesser quality material gloves do not receive the 2d6 medium weapon bonus, but rather a regular 1d6 (same applies to the large bonus).
