Arcane lore returns after more than a year off, to give them another place to fit in new spells. Not that I've missed it with the Wizards Three taking up the slack. And since this is another collection of elemental and energy based stuff, it seems pretty obvious they haven't been getting any cool new submissions in the department lately. Like the ecologies, things sure aint what they used to be round here. Send more stuff in!
But enough pessimism. Let's talk about the good aspects of this article. For a start, it's fluff is set in Greyhawk, rather than the more usual FR stuff. Also, there's a decent amount of planes related stuff too. And all the spells are pretty handy for an adventurer. The worst that you can say about it is that it's a little formulaic. And that's hardly a surprise at this stage.
Frostfire lets you make your torches and bonfires heatless or actively cold. This'll keep you safe, or allow you to bypass many monster's energy resistances. That'll intimidate those red dragons.
Proficiency lets you use weapons you don't know how to, even violating class restrictions. (although gods'll still throw tantrums if their clerics break the rules. ) This is of course most useful to the wizard who casts it. Don't think you can go toe to toe with a fighter though. Hubris will get you.
Bands of Ice are your basic unpleasant magical imprisonment method, which'll also give the captive frostbite. Ahh, the joys of bend bars/lift gates rolls to escape. If anything says they don't actually want you to succeed, it's them.
Lightning Curtain is basically the electrical variant of wall of fire, with it's own variant on being drawn to metal, and being more dangerous to those wearing it. Another one to help wizards be smug in their lair when facing fighters.
Lightningcloak is a little more inventive and a lot more versatile, serving as both offence and defence for it's wearer. There is a compromise in that the protection ends when you discharge all the energy, but that's no biggie as you're unlikely to run out of other spells to blast in the interim at this level.
Death Shroud taps into negative energy for a similar, but even more powerful bit of garb that has a pretty decent chance of killing anyone who touches you. It does have rather expensive and hard to find material components though. Not one for casual use.
