Crystalbug is a fiend/crystalbug-type enemy in Final Fantasy XII. There are only three Crystalbugs, a red, blue, and green one. The player can steal Feystones from it, needed for making High Arcana.

The first mention of such a creature comes from the moogle merchant Tetran, who mentions a creature that mimics crystals.

The blue Crystalbug is found in the Acolyte's Burden in Sochen Cave Palace and poses as a legitimate save crystal. It becomes an actual save crystal when defeated.

Clan PrimerEdit

Page 1: ObservationsEdit

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.

In the original Japanese version, the blue Crystalbug had 3,589 HP and 32 Defense. Both the Piggyback and Bradygames guides erroneously show the stats from the Japanese version. The overseas versions' stats are used for the Zodiac versions. The Original Japanese Guidebook, meanwhile, cites the Blue Crystal Bug's MP as being 2750, but subsequent guides list it as 999.


The blue Crystalbug knows elemental magicks, halves all elemental damage, is immune to all negative statuses and has the troublesome Restore ability. Like Mimics, it will not attack until inspected. The blue Crystalbug does not give any Experience Points, but does give 10 License Points.

The Crystalbug must be attacked consecutively, as otherwise it will resort by using Restore to heal itself for 30% of its HP.

This Crystalbug can be defeated regardless of whether the party has buffs or not.
