Call sword probably doesn't need its own level, maybe combine it with level one.
Warrior's edge, warrior's shield, increased senses, and rally call could probably reduced to take up fewer levels. Maybe a skill that lets you change to different auras, one for attack, defense, senses, and support.
Flare could be buffed up some.
Maybe just one level for switching blade elements.
Suggestions above should give you more levels to play with to add more impressive skills to later levels.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
