I think they just about said it all. Do note that is your specialazation ended up in something other than alteration, you might want to reset them. I believe the quest to do that starts in temple off of Lavastorm. As a cleric, we have all the casting skills, but the one needed the most at high levels is alteration, due to groups aversion to letting the cleric cast dmg (it can be hard to cast dmg anyways due to resists). So if you have something other than healing, i segest you change it, then sit there with a mid-level heal and just cast and cast and cast until it breaks 51.
Just like to say that i have maxed skill in almost all spell skills (working on conjuration) and i only fizzle about once in 100 maybe 150 casts. Needless to say its EXTREAMLY rare.
