Riftmarked Feat 1
Source Pathfinder Lost Omens: Ancestry Guide
Long ago, qlippoth marked someone in your lineage, most likely through their ancient runestones that dot Golarion's surface. Yours is an old lineage, primordial and twisted, and you have a sense for similarly twisted things. You're trained in Occultism. If you're already trained in Occultism (from your background or class, for example), you instead become trained in a skill of your choice. You also gain the Oddity Identification skill feat.
Note: If you are already trained in the skill provided by this feat, you need to manually select an alternative skill. You also need to manually enter the granted Lore skill.
