I frequently want to compile a list of monsters with a specific Special Ability, but doing so currently involves numerous Pfsrd searches and sorting through massive piles of noise, followed by fine-tuning for probable things that a SRD search would miss. How can I do this more time-efficiently?
The site www.archivesofnethys.com has a well working search option. By giving the name of the special ability, for example earth glide, and checking the monsters box you should get an output of all monster descriptions including earth glide.
If a spell with the same name exists it will come up with monsters with that spell listed, too. As do those whose description includes your search term. But I use it on a regular basis to look for monsters with certain abilities.
