Good Ring of Spell Knowledge Picks?

[Zanos]

So the Ring of Spell Knowledge (http://www.archivesofnethys.com/MagicRingsDisplay.aspx?FinalName=Ring%20of%20Spell %20Knowledgetype%20I) is an interesting magic item that lets you pick up off-list arcane spells at SL+1. Trying to get some mileage out of it. Since they exist for up to 4th level spells, this lets us poach spells of up to 3rd off the list of other arcane casters.

Thoughts so far:

Ill Omen (http://www.archivesofnethys.com/SpellDisplay.aspx?ItemName=Ill%20Omen) from the witch list is a solid spell that's basically a no save misfortune. You could quicken one of these in a sixth level slot and then toss out a SoD in the same round for a pretty nasty combo. It's also just a generally solid debuff, even as a 2nd level spell.
Glibness (http://www.archivesofnethys.com/SpellDisplay.aspx?ItemName=Glibness) from the bard list, because for some reason they didn't nerf the +20 to bluff spell.

Any other ideas?

Assuming you're starting as a sorcerer you have access to the best list around anyway; you may be better to treat it like a page of spell knowledge that you can reprogram before each adventure.

If you really want to use the other spell list feature though, Vomit Swarm is a standard action summoning spell, which would still be worth a 3rd level slot.

They didn't have to, because they nerfed bluff itself:

"Note that some lies are so improbable that it is impossible to convince anyone that they are true (subject to GM discretion)."

Ergo, no yellow-footed rock wallabies. (http://www.giantitp.com/comics/oots0767.html)

Glibness was actually nerfed twice. 3.5 version gave +30 to bluff checks, PF version is +20.

I use it for Barkskin (summoner 2, even unchained) on my Eldritch Scion Magus in PFS.
