As I said, feel free.

While there are many types of elements outside of these, Electricity, Fire, Steam, Wind, and Light are the most used.

"Spells" use the elements directly, in forms such as steam bursts, arcing electricity, or fireballs. 
"Enchantments" are used to give more power or versatility to a tool. For example, an electric bow could be used to take out a system.

Electricity is the most versatile of the elements, capable of charging most weapons and just plain out zapping everything with giant arcs of electricity.

Fire is either a slow-burn that lingers on an area, like a molotov, or a large cloud that dies as soon as you cut the power. Fire is rarely utilized as an "enchantment" for weapons, but is very destructive.

Steam, like Fire, has high defensive and offensive capabilities. Although it has much higher efficiency, it is much easier to go through, as it cannot set objects alight. While more used than Fire for enchantments, it is still rare.

Wind is utilized by using a modified fan. It can be used to blow others away, accelerate an object, or to travel at high speeds.

Light itself is generally not a very good weapon. Lasers need to be held at the same spot for seconds before it can do anything. Rather, it's used to blind people, making it a very popular enchantment for CQC and for defense.
