Hmm, i'm curious how golarion lore is going to explain magic and culture with some of the charisma penalty races like dwarves and most 1st level monsters.
What's a good explanation as to why dwarves, or any race with a charisma penalty, make magical items when they can't use them?
Do merchants with magical wares just not go to dwarven or orcish towns?
Norse mythology ties dwarves to the forging of magic items, such as Thor's hammer Mjolnir and the Ring of the Nibelung. These were the most renowned of the dwarven smiths, which implies a level with more than a single resonance, despite a Charism penalty. Nevertheless, an impression that dwarves shun magic items will conflict with the mythology about dwarves.
Thorin Oakenshield had no trouble claiming the magic Elven sword Orcrist, the Goblin-cleaver, from the troll horde in The Hobbit. But weapons don't require resonance. Maybe that is the key: dwarves have affinity for magic items that don't require resonance, such as magic weapons. I wonder how that could be represented as a dwarven ancestral ability.
Maybe I'm mixing something up but aren't D&D legacy dwarves traditionally bad with magic, even though the mythical origins are good with it?
