Primarily a physical attack type among the four Basic Class Homunculi, Filir is potentially the fastest, sporting impressive attack speed and flee rate capabilities. His skill pool is specifically tailored to take advantage of these traits, either increasing physical damage or further boosting already intimidating speed values. Of noteworthy mention is S.B.R.44, arguably the most powerful single hit attack of all the Homunculi: but at the cost of almost all of its Intimacy.
There are only 2 species of Filir. Transforming Filir from its adolescent appearance into a mature form requires a Stone of Sage when it possesses loyal disposition towards its creator.
