Ganzi
Source Pathfinder Lost Omens: Ancestry Guide
Your blood is touched by primal chaos. You gain the ganzi trait in addition to the traits from your ancestry. You gain resistance to a single damage type equal to half your level; at the beginning of each day, determine randomly whether this resistance applies to acid, electricity, or sonic damage. You also gain a +1 circumstance bonus to saving throws against effects that would cause you to gain the Controlled condition. You can choose from ganzi feats and feats from your ancestry whenever you gain an ancestry feat.
