You have either trained, formally or informally, under a master
of arms or have otherwise come to earn mastery over nearly any
weapon you come across. You gain proficiency with all simple
and martial weapons. When you take this talent, if you already
have proficiency with all simple and martial weapons, you
can instead choose to progress again on this tree rather than
gaining weapon proficiencies.
