In the chat he was saying it wasn't a +2 weapon either, but the +2 is still being applied to Berg's damage and hit rolls.
Some clarification needed.
The consequences of Farang not having access to magical damage means golems and lycanthropes should shit on their parade, depending on how their anti-magic bubbles work.
My personal favorite anti-farang creatures, the Androsphinx. Immune to bludgeoning, slashing, and piercing from non-magical weapons and psychic damage. Coutals have the same, but are celestials thus probably can't perceive Farang (thats a rough encounter for CR4, immunities + high AC + good saves, luckily it's good aligned).
