But I have an idea that is quick and easy to implement. Some of the effects are actually already in the game! I am of course talking abut using the Shouts. Let me give an example
Fus-Ro-Dah (Unrelenting force) The power of the Thu'um knocks over anyone in its path.
Now let me show you an idea for a "force" series of spells.
School: Destruction
Novice Spell: "Push"- A close range spell used to briefly stun an enemy. Can be resisted by blocking/wards
Adept Spell: "Shove"- Another close range spell that can stun an enemy, even through a shield. When Dual-cast can knock them over.
Expert Spell: "Applied Force"- A projectile spell that when it hits an enemy, will knock them over. Dual-Casting will increase the effect, or give it a small AoE.
The Novice spell push, I thought, was quite nicely balanced for beginning gameplay, as it deals no damage and can be useful all around for mages, warriors, archers, ect. And it could only really be used to interrupt an attack as it won't go through a block.
The Adept spell is a nice step up, allowing you to stun anybody, and with the nice benefit of dual-casting greatly improving it to knock people over, allowing for a quick getaway, or time to launch a new attack.
The Expert Spell "Applied Force" is the final in this series of spells and gives the greatest effect. When cast, after a brief charging period, it launches a small bolt of force, capable of tossing foes. Now this would need a corresponding magicka cost, but well worth it.
Now I'm sure your probably asking yourself, isn't this redundant with the Shout, capable of all of this? No, and heres why. The "force" series of spells only affect 1 target, thus rendering it unique from the shout, which can toss around a group of foes and (rightfully) requires a cooldown. This series is better for smaller encounters, or if you prefer to have another shout equipped, this could help mix up gameplay.
So any questions, thoughts or ideas?
