Oh please, don't make her magician or something like this! I hope "making stronger" in this context means not the power of magic or strength, but some knowledge or something like this.
Cause what's the point in making her literally stronger in the first place? She gonna fight with dragons? What for? And the power can't solve everything anyway. I mean, there is Tooru - one of the most powerful dragon out there and it's not like her power helps to solve relationship problems.
