I'm looking for a shorter module based in abandoned, magical ruins for a roughly 10th level party. I'm hoping to replace/add to the Acropolis of the Thrall Keepers in the Curse of the Crimson Throne. Unfortunately, other than the initial Havero combat, I find it a little underwhelming, and would prefer something with more puzzles and combats with weird creatures.
Any suggestions will be much appreciated!
While hitting only some of your requests ... I recommend The Harrowing by Crystal Frasier. It's designed for four 9th level adventures and ... well, WEIRD, is the name of the game. My group talked their way around MOST of the combats, but there is a lot to love there.
While I don't know most of the modules, this page, sorted by level may help narrow things down.
Here are all the adventures for 10th-level PCs available for PFRPG in the Paizo store. Several of them seem to deal with exploring ancient cities/dungeons. You might skim the descriptions and reviews to look for something likely.
Thanks for the tips!
Crucible of Chaos may be what you are looking for. Though for the 3.5 line, most of the monsters are now in the Pathfinder "canon" so it's easy to convert on the fly and it's loads of fun.
