All looks good, cept for the Skill. Yea, some sort of supernatural power (or just having flaming bolts) would be required for something like that. 

I guess I could suggest the same sort of Skills I suggest for Ominal if your focus is going to be ranged weaponry. 

Aim (Lv 1: 0/100 XP) (Active: 10 MP): You focus and take careful aim at your target, allowing you to fire into a melee without accidentally hitting an ally by focusing your aim. Also when using this Skill, it can be combined with other Skills that affect your ranged weapon. If used on a foe who isn't in melee, you instead increase the accuracy of your shot by 1. This cannot be used on enemies close to you. To Level Up: Use this Skill, Hit an Enemy, Defeat an Enemy, Score a Critical. 

This, or

Proximity Shot (Lv 1: 0/100 XP) (Active) You can use a Ranged Weapon on enemies closer to you to increase damage, plus you fire and aim at such a speed where you are not open to counterattacks. Firing at enemies closer to you increases the damage of your Ranged Weapons by 10%.
