I'm playing a rogue 3/ sorcerer 1 as a prelude to an arcane trickster. Since I expect to be spending more time in melee than most spellcasters, I want to have pretty good AC, but the armor I have now (studded leather) has a 15% arcane spell failure chance. I checked out [this question](https://rpg.stackexchange.com/q/18468/5953), but most of it only applies to 3.5, and I'm playing pathfinder.

**How should I deal with arcane spell failure from armor in Pathfinder?**
