[@Vongola_Hasayo] According to the wikia it's called sword magic (the summoning forth of Erza's swords). Also, while Sword Magic is mostly about bringing forth swords, Lucas's blade magic can also launch his weapons. It looks small but it could have a huge impact. (Think summoning like 30 gates and all launching blades, basically showering sharp metal). I based it more off Fate/Zero's Gilgamesh's power.

Also, I'd like to replace reaper with this:
Lost Magic: Spirit Lord - After the encounter with the Reaper, Lucas' senses were forever changed. Suddenly he started seeing dim lights where non where. Strange disortions traveled through his world suddenly. Spirits that nobody else could see. What these spirits exactly are, he doesn't know. Ancient theories suggest they are the floating remains of life. Others say they are odd essences coming from a certain power. Whatever they are, they can be used.
[hider=Known spells]
[i]Spirit Beacon[/i] - Lucas can turn his body into a magical beacon for the spirits. Normal people won't seen anything different (other than the fact that he's meditating). To maintain the beacon he needs to draw both mana and remain focused. So doing it in battle is nigh impossible. This is mostly a utility skill to gather the spirit power.
[i]Imbue: Elemental spirit[/i] - Lucas can use his gathered spirits (or a portion of it) to imbue his weapons with their magical energy. The basic energies he can imbue with are the 4 elements: fire, water, earth and air. After a few minutes the spirits will vanish from the weapons.
[i]Imbue: Mana spirit[/i] - Fusing the spirit's their energy into a mana spirit takes more energy and magical power. However, the result is worth it. Mana spirits imbueing already magical weapons vastly increase their natural elemental energy.
[i]Medium: spirit nova[/i] - Lucas allows the spirit around him to materialize. Using him as a medium to do so. During the brief moment they are in the corporeal world, they gather immense amount of magical energy. (this also puts a strain on Lucas). So much magical energy that it blows up after 2 seconds.
[i]Medium: River Styx[/i] - Lucas uses his own body as a spirtual focal point, just like Medium: Spirit Nova. However, he uses evne more magical and spiritual power to create a focal point further away from him. After that he allows the spirits to materialize around him. Creating a flow of 'mana burning spirits' between the two focal points. It's a very powerful and destructive magic. One he hasn't fully mastered yet.
[i]Medium: Incorporeal[/i] - Instead of pulling the spirits into the corporeal world, Lucas draws himself into the spiritual world (which basically is ours but with spirits in it). He turns incorporeal and invisible (except for a faint shimmer where he is). He cannot be attacked nor can he attack anyone. He can move himself into safety or use it to flank opponents. Right now the Incorporeal form doesn't last that long.
