Crystalbug (red)

The Crystalbug is a fiend/crystalbug-type enemy from Final Fantasy XII. There are only three Crystalbugs in the entire game.

Bestiary Entry
Genus: Fiend Class: Crystalbug

Page 1: Observations
"Being a fiend that, unable to move and hunt for food on its own, mimics the form of a crystal, thereby tempting its prey to come to it. The deception is nearly perfect and thus almost impossible to detect. Should an ill-starred traveler mistake such a creature for a crystal, and reach out his hand, he will be treated to a maelstrom of the strongest magicks, before having his life juices summarily drained."

Battle
The first mention of such a creature came from the Moogle merchant Tetran, who mentions a creature that mimics that of crystals. One can be found in the Walk of Revelation area of the Stilshrine of Miriam, appearing as a curious green crystal. Another in the Acolyte's Burden in Sochen Cave Palace acts like a legitimate blue Save Crystal. The third one, looking like a Gate Crystal, can be found in the Succor Midst Sorrow area in the Nabreus Deadlands.

They will not attack until inspected by the player. Crystalbugs are somewhat difficult and do not give any experience points, but they do give 10 license points and become actual save crystals when defeated, so they are worth fighting.
