[@Raddum] Yeah, the Max level will be lv 100, meaning you can have skills ranging from lv 1 which would be the basic skills to lv 100 being the most powerful and advanced.

Now let's see if I can help you here. You are a Wavemaster who focuses on Elemental Magic so think Avatar, just with magic.

Meteorites, you can do it.

Tornadoes

Lightning Storms

Tsunamis

Molten Lava

Etc. These are just a few examples. You could also use Dark elemental spells and Light elemental spells. You don't have to stay completely canon.
