Effect: The user coats their blade in wind magic causing it to look like a mini tornado that is .5 meter in diameter. Each swing of the sword will now fire out a 3M wide blade of wind that is 1m in diameter up to 10 meters that will cause deep cutting wounds on impact. Kaiser is able to fire off 6 wind blades before the spell is cancelled.

Should be good.

Hello, Kaiser.

Wind Wall: A D-class shield can only block spells that are equel in rank, a C-class spell will break the shield. "For fire, water, and gas it can block 1 B rank, 2 C ranks, and 4 D ranks. For metal and earth it can only block 1 D rank spell." You can leave this part out of the description.

Wind Current: Change 50% to 25%. D-class buff spells have a 25% buff.

Cyclone: Change it to 1 meter tall and 1 meter and 0,5 meter in diameter. It is either a offensive spell, being able to cause damage. Or a supplementary spell, being able to buff, debuff etc. Pick one.

Whirlwind: Change 5 meter high to 1,5 meter high and 0,5 meter in diameter.

Zepher Blade: How long and what is the width of the blade? It can not be 5 meter.

updated. I don't know if an element chart is implemented or not but that is what I did for the defensive spell for the strengths/weaknesses. Updated by your requirements though.

Wind Wall: Defend against 2 D-class spells.

Zepher Blade: Add the width and lenght of the blades. How many blades are you able to send out with this spell?
