General Overview

Introduction
Felkin focuses on raw power basically.  So out of Fuwa, Dagos, and Felkin, Felkin users have more attack power than the rest.  Most of Felkin's affinity skills focus on short duration buffs that deal with your attack, defense, evasion, etc along with some other nice skills.  If you can max all these skills out and use them correctly on the battlefield, you can be a unstoppable monster depending on your skill build also.

Felkin are strong against Dagos users and weak against Fuwa users so depending on the server, this can be good or bad.
