I'm starting a new game as a fifth level artificer (and fifth level wizard so I had WBL for a level 10) and was trying to figure out what magic items I might want to spend my WBL on. However since Pathfinder has 1544 wondrous objects and presumably only some of them have a caster level requirement less than or equal to 7 I haven't been able to find which ones I should even be considering. Does anyone know of where I could find a list by caster level?
A convenient, easy-to-sort, free, quick-loading database of wondrous items that's organized by caster level may exist somewhere, but this reader suspects that such a database won't be of much help
It sounds like the issue here is the belief that a magic item's listed caster level is a requirement for the magic item's creation. In fact, this is not typically the case: The Pathfinder SRD on Magic Item Creation, in part, says "A creator can create an item at a lower caster level than her own, but never lower than the minimum level needed to cast the needed spell [that's required to create the magic item]." Hence only those magic items that have a caster level as an actual requirement for their creation require the creator to possess that caster level; other magic items can be created so as to possess a caster level anywhere from the minimum caster level needed to cast the spells required for their creation to the caster's actual level. (However, note that creating a magic item at lower, nonstandard caster level may affect the magic item's performance.)
For example, a cape of the mountebank that normally has a caster level 9 can be created by a level 7 wizard who's capable of providing the cape's required dimension door spell because having caster level 9 is not a requirement for the cape's creation! When that wizard 7 creates that cape, that cape has both a minimum and a maximum caster level of 7. (Such a cape's range—and perhaps capacity—would be similarly altered by this lowered caster level to a degree that would make it inferior to a typical, off-the-rack cape of the mountebank, by the way.) However, a typical ioun stone has as one its requirements that the creator actually possess a caster level of 12, making that requirement fixed and—without bypassing that requirement by increasing the Spellcraft skill check needed to create the item—inescapable.
In sum, a list of wondrous items that themselves possess a caster level of 7 or less doesn't actually give you a definitive picture of what wondrous items your PC can create. However, a list of wondrous items that includes their spell requirements would.
Note: I can't vouch for the completeness or usability of this database (last updated Dec. 2017) nor this database (last updated Mar. 2014)— both of which are massive and take a long time to load—but they seem like the kinds of thing that might be of help.
