Moving on, I would love to see Spell Faultering brought back in Skyrim. Imagine this scenario:
"You move against a vicious mountain troll. He swings his mighty fists left and right in a violent rage. As you roll back to dodge, your hands glow red to prepare themselves for a new fire spell you learned the previous day. When you cast your magicka, the spell faulters and a tiny spark singes out. You suddenly wish you had practiced your destruction magick as the Troll moves in for the kill..."
Basically having this would mean the player really needs to have the required skill level to cast magick spells or backfire/mishap could happen. Thoughts?
