Bloodline Arcana: Whenever you cast a spell with the
cold descriptor, you may select one target of the spell to be
slowed (as the spell) for 1 round. A Fortitude save (DC 10 +
the level of cold spell + your Charisma modifier) negates
the effect.

Rime Spell (Metamagic)

Creatures damaged by your spells with the cold descriptor
become entangled.
Benefit: The frost of your cold spell clings to the
target, impeding it for a short time. A rime spell causes
creatures that takes cold damage from the spell to
become entangled for a number of rounds equal to the
original level of the spell.
This feat only affects spells with the cold descriptor. A
rime spell uses up a spell slot one level higher than the
spell’s actual level.

So for the small cost of either a Rod of Rime Spell or 5 (or just swallowing that +1 slot), a sorcerer focusing on [cold] magic can potentially slow a target, and will entangle their target.

I was hoping to find some [cold] [sonic] spells to get Concussive Spell in on the action, but there appear to be none!

If you are willing to take a 1-level hit to your caster level, dipping Oracle for the Waves Mystery makes an excellent choice for cold-based casters. They can take the following revelation from the Waves mystery.

Freezing Spells (Su): Whenever a creature fails a saving throw and takes cold damage from one of your spells, it is slowed (as the slow spell) for 1 round. Spells that do not allow a save do not slow creatures. At 11th level, the duration increases to 1d4 rounds.

Now, I'm pretty sure that the Oracle revelations apply to all spells you cast, not just your Oracle spells. I recall seeing a ruling to the effect in the past, but I can't remember where I saw it. Freezing Spells is almost always better than the Rime Wildblood ability, as this applies to every creature who fails the save vs. your cold spells. That said, nothing says that they can't both be used at the same time. The small downside is that it only activates on a failed save, so no Slow from a Ray of Frost.

Another take on this would be to take the crossblooded archetype and select the Rime-Blooded and Cold Elemental Bloodline. The Cold Elemental Bloodline will allow you to change any elemental spell into a Cold spell when casting it. You won't be able to get the entangling effect, but you won't need to use metamagic, either.

The elemental bloodline changes the type of the spell to whatever your elemental nature is, so yes, that would work. I really wish Elemental Spell wasn't +1 level though, because splitting the damage type could allow for interesting combinations of rider effects.

You could just take eldritch Heratige. Requires skill focus as a pre-req, but could be worth it.

Eldritch heritage does not give you the bloodline arcana, only the bloodline power, I think.

Correct. Jason B clarified that. So many dreams of mine were shattered upon reading that.

Aww, crap. You are correct, sir. Oh well.

Have to say, the combo looks pretty slick. I might whip together a build to see how it looks on paper.

What was that one new ice spell from UM? I believe it was a cone of cold-like one that could be cast with a swift action, if I remember correctly.

Related question: Does the Ice Scorching Ray you get as an elemental bloodline sorcerer work with Rime Spell. Might be nice to entangle something 2 rounds with no save.

Seeing how they gave a guidline for creating spells, I dont' see why one couldn't research a "Frozen Ray" that is identical to scorching ray with the exception that it is cold damage.

This being the case, I would say yes.

My sorcerer being a PFS character, custom spells are right out.

In that case.../fail. lol

Actually, at level 5 water elemental sorcerers get a scorching ray that has the [cold] descriptor, as per their bloodline arcana. This should trigger the bloodline arcana of the Rime-Blooded bloodline, or as you asked, the Rime Spell metamagic.

I believe so, anyway.

For added fun - play an Undine.

Yes, I do believe Crossblooded Water Elemental and Rime-blooded may be the best option. Or Marid.

Either that or you can stick to just Rime-blooded and pure [cold] spells, and not take the hit of Crossblooded. Elemental Spell adds one to the level, so I'm not going to consider that.

If someone does come up with a character based on this, I'd love to see it!

The Toppling Force mage might be better at controlling though. They don't get the nice Slow effect, but can knock prone 5 guys at range pretty easily.
