Well my character, Chinoki, is skilled in both hand and magic combat. Their weapon of choice are knive. Their magic is a cross between enchanced agility and speed plus they can summon knives to use has either defense or offence. I would show you a CS but I don't have that typed up in a forum yet because it's currently saved in a doc. 

I have now clue about Arena's but my best guess would be a open area because that's what they fight best in. 

I have no clue in how ranks work honestly, so you can figure that part out.
