Finally, the Spell section is open.
OK here are some spells I had problems with just by looking at them due to the fact they haven't been changed since 3.5 or changes are a bit too good
Mage's Disjunction: Changes have been nice, but make the duration instantaneous and mention the dispel time in the text in order to keep the party/enemy from dedispel the disjunction's effect.
Maybe the duration could be 1h/level or even 2h/level, since friendly fire should be a real menace, not just a little thing to concern. (Well maybe the 5% chance to ruin the item does the trick, I haven`t seen the new version in combat yet, it's hard to say because it is more a psychological problem)
Rusting Grasp: Needs a touch attack. It's common in 3.x DnD but since it is more like a sunder than any other spell, why don't use the CMB system? Make it an attack to CMB with a bonus to +1/level (if that seems to make the CMB quite easy, remember how often a mage misses a touch AC. Often in low level, almost never in midlevel, highlevel... well depends on the DM)
Additionally for quickness sake a note could be added that dispelled magical items qualify to be effected.
Antimagic Field: A question that always concerned me and wasn't ever clarified: Does AF break Line of Effect? Does a lightning bolt stop in an AF or springs it out of the other side again?
