warpriest sacred eapon

[daimaru]

As a level one warpriest I choose a falchion as my sacred weapon but can't afford to buff it up as a master work. Can I later buy a master work falchion and use it as my sacred weapon? Or am I limited to the original one?

[Ross Byers]

As of the playtest, any weapon with which you have Weapon Focus is a Sacred Weapon.

So, yes, if you later buy or find a masterwork falchion, it will work as a Sacred Weapon.
