Mimics are magically-created creatures with a hard rocklike outer shell that protects their soft inner organs. Mimics can alter their form and their pigmentation; they use this talent to lure victims into close range, where they attempt to feed on them.
They usually appear in the form of treasure chests. There are two varieties, the smaller, more intelligent common mimic, and the larger, less intelligent killer mimic. Mimics are large. Common mimics occupy about 150 cubic feet (a 3' x 6' x 8' chest, or a large door frame). Killer mimics occupy about 200 cubic feet.
Mimics' natural color is a speckled grey that resembles granite. Mimics can alter their pigmentation to resemble varieties of stone (such as marble), wood grain, and various metals (gold, silver, copper) it takes one round to make the desired alteration. They cannot lose mass in this transformation (they must remain the same size, though they may radically alter their dimensions).
Common mimics have their own tongue (corruption's of the original language spoken by their wizard creators) and can also be taught to speak in common and other languages. Killer mimics are incapable of speech.
A mimic can surprise its victims easily. When a creature touches a mimic, it lashes out with a pseudopod that inflicts almost irreversible damage. Furthermore, the mimic covers itself with a glue-like substance. Any creature or item that touches a mimic is held fast. Alcohol will weaken the glue in three rounds, enabling the victim to break free. A mimic may neutralize its glue at any time that it desires; the glue dissolves within hours after the mimic dies. The mimic is immune to acid attacks and is unaffected by molds, green slime, and various other weapons such as bombs or short swords.
Mimics live underground, where they can avoid sunlight. They are solitary creatures; this is to ensure that each mimic has a large grazing area. They have no culture; their primary concerns are survival and food. Common mimics are quite intelligent and will gladly offer information in exchange for food.
Killer mimics attack regardless of attempts at communication. Mimics have no moral code and no interest in culture or religion. Wizards who use them as guardians have sometimes found them to be less than enthusiastic about obeying their commands.
Mimics were originally created by wizards to protect themselves from treasure hunters. A good meal (one or two humans) can sustain them for weeks. They reproduce by fission and grow to full size in several years. Mimics pose as stonework, doors, statues, stairs, chests, or other common items made from stone, wood, and metal.
Their skin is covered with optical sensors that are sensitive to heat and light in a 90-foot radius, even in pitch darkness.
