Magic items are extremely rare and only the most capable and powerful people in the world have them. Most magical items are personal and only affect the individual, so personal magic items are in feel for the game. Wands and Scrolls are pretty much nonexistent.
Spellcasters are also extremely rare and hard to come by. Most belong to an organization proper or are very aloof. Witchers and spellcaster are mutually exclusive terms since no magic wielders are ever accepted into Witcher schools.
With the exception of Potions (which often kill when used on normal people), magical healing and magical items that are capable of healing are non existent.
Extraplanar creatures are incredibly rare and the “planes” as defined by Pathfinder don’t really exist in this world.
