I am currently playing a level 5 Winter Oracle in my current game. I have seen a few examples around online where an Oracle takes 1 level of Sorcerer for the Arcana. I was wondering if it was really worth it or whether it was a wasted dip.
I'm playing a Winter Oracle as well; a dip into Elemental Sorcerer really helps expand the spells you can use to slow people. The Winter Oracle bonus spell list is really bad for abusing Freezing Spells, so the best thing to do is convert other spells (such as all the fire spells you get from the blackened curse) into cold spells.
