The Vulcan is an enemy from Final Fantasy III. It is found in the desert area of the Surface World. They have decent power, having access to the tier-2 Black Magic spells. However, because they have little HP, they can be dealt with easily with physical attacks. In the DS version, they attack the entire party with Fire Breath, and should be dealt with quickly to avoid being wiped out.
When first venturing out from Amur, the party should avoid trekking too far to the east, as these monsters may prove too difficult at the party's current level.
