No eletricity? Thats wierd... We use all the traditional elements and forces of magic but not the 5th element \'Electricity\'
Electricty, Earth, Wind, Fire, Water, Light, Dark
Electricty is a thing that needs to be added.
Electricty is powerful and hard to control, only the most powerful of Sorcerers master the power of Electricty. They are usually partnered with blacksmiths to make weaponry to channel the Electrical element.
When other elements are combined with the Electricty element, if not controlled properly could kill you.
Water and Electricty, if there is a stream of water connected with you or close to you, and a powerful current of electricty is added, it will effect you as well as your target.
If earth element and Electricty are not properly channeled, then you will end up creating a useless spell.
Also I think there should be more \'Material needs\' in spells. Such as a teleportation spell that requires a placement of a target object, and the use of some powerful rare material, such as 5 gold fire swords. You need the gold and magic of the weapons to generate the powerful spell.
Also, with technology, you can create a steam engine that is small. Using magic. I also feel that magic, tech, and physical powers need to be more balanced in this. Like if you train in one point of Intellegence you lose one point of strength. If you train in STR you lose INT. If you train AGIL you lose WILL. Something like that. Maybe not exactly that

but something similar. Also at character creation you should have to choose if you want to use spells or not. On this Scale-
Techer- low weapons, No spells, Best with Spells.
Fighter- No magic, Low Tech, good with every weapon.
Magic- low tech, No Weapons, best with spells.
Techer/Fighter- decent with most weapons, knows most tech but not best with it.
Techer/Magic- Decent with magic and tech.
Magic/fighter- Decent with some weapons, knows alot of magic.
Also you can go more prestige-
Monk- Magic fighter- No weapons, No armor, Great Magic, Best Melee fighter.
Jack of all trades- This is the only class that can build unique machines, spells, and weapons. Such as, A machine fighter that casts spells, and a weapon that casts spells.
