Legend
I don't understand what you mean?Going by this thread, I was under the impression that it was a new option, akin to a new choice being presented. Adding a new option wouldn't change the functionality of anything already in the book.
If I was reading that incorrectly, and he's just sneaking in a new core feature of the Beastmaster so "at level 7, your animal companion counts as a magical weapon for the purposes of bypassing defenses", then that would be a real change.
If you want to interpret this as the Ranger or his companion keeping the choice of remaining unmagical, sure, go ahead... but what good does that do you?
