@Kryosky The skills for magic users are more super-buffs than they are a power in themselves. A magic user can only control their element to a certain extent (shooting your element from your hand, making a shield out of it, creating a surface of it, etc) but the skills allow them to make supernatural occurances of their element, with dailies at epic proportions (hailstorm, rain fire, call lightning from a cloud, kill someone with their own shadow). An earth Mage (magic user) would normally be able to command nearby land as far as editing elevations by a few feet or pulling rocks from below the crust to chuck at people or accelerating plant growth to trip someone. Your skills might be:
instant: form a diamond under you in the shape of a weapon and are able to use it
encounter: create a 5-foot diameter quicksand area in front of you
daily: create a fissure in the earth under someone's feet
You can make your own, but instants are more buffs than anything, encounters are empowered attacks, and dailies are along the lines of a localized natural disaster.
