Feats are challenges that award feat points upon completion. For every 100 feat points achieved the player will receive an additional skill point for their character. Each feat has a star rating, which reflects the difficulty of accomplishing that feat
A player must have at least 90 skill points for their characters role to work to its full potential and unlock main weapon and cross-weapons mastery. However, getting more Skill points will let them get additional Weapon Masteries points and make characters stronger.
