The detect magic wears off.
Doesn't quite seem like a proper sentence...something like "You no longer sense magical auras." maybe?
You intone an ancient mystical chant.
Your lightning bolt DOES STUFF to Someone!
Which lightning bolt?
Most spells give a message, like, "You send a sliver of ice flying at Someone." or whatever (not actually checking it right now.) Maybe have something for this, like,
You intone an ancient mystical chant.
You release a bolt of electrical energy at Someone!
Your lightning bolt DOES STUFF to Someone!
Finally, just about the Wall of Ice again...there was a post in bugs about bleeding, bashing, etc. against it. I haven't checked, but what about effects (stuns) from spells? Like Crushing Hand, Meteor Shower, Fork Lightning, etc? Can a wall of ice be hammered to the ground, or stunned by the impacts, or convulse from the massive shock?
(Maybe this is taken care of, thought I'd mention just in case it was overlooked.)
