I have some things to tell you however about her fourth skill. Dispelling magic is hard. For example, a decent magical barrier has a lot of magical codes implanted by its caster and, in order to undo it, one must either studiously decode the magic and imbue her weapon with the counter-code, or brute force it using stronger magic. 

She could have that skill with no problem if she is a prodigy or has been studying magic for decades, which I think is kinda impossible given her age. 

I am currently thinking about a way to compensate this by introducing the artifact system. Along the journey, players may loot weapons or trinkets with effects that can grant similar effects to her fourth skill. That will also give the player a sense of progress and make every finished arc feel more rewarding.

The character is based on Pathfinder's Magus, so I think I'll just switch that ability with another one. Probably the spell that elongates the weapon up to 6 meters as a whip-like weapon. But it's up to you.
