I'll allow air shot but I don't think the tornado techniques would be something Fer could learn from the shield he'd have to deactivate his legendary weapon to use it just like how Naofumi had to learn. Also we'd be roughly level 10/13 or so post this upcoming timeskip, the tornado would be effective against common citizens and arrows but it'd be weird if a tenth level mage could rag doll trained warriors in armor quite so soon. At least it would be a small radius. This is not because I think they're strong but simply gripes about lore, and level reasons. 

Dark/Light are two separate elements in my opinion please choose one of which. I'm only allowing two and your other would be wind. Unless there's some sort of lore i'm forgetting about that supports light, and dark being two of the same.

Also you're learning all of this in five days? Which will roughly be how long the training will be?
