Ancient Crystals are stones found all over Bugaria, rumored to have first been found by the Roaches before they mysteriously disappeared.

These crystals always emit light and can be seen even in the darkest of caves. They have the ability to record their surroundings.

The party can hit them with a field skill to activate them.

Yellow Crystals are also able to heal the party upon being hit.

Many kingdoms use crystals as power sources, and the Ant Kingdom has a huge mine underneath the Anthill Palace to obtain them.
