Looking at the Weapon Master Fighter Archetype, there's a few things missing from a couple of the descriptions.
Firstly, Weapon Training. It replaces Armour Training 1, 2, 3 and 4 at their respective levels, which is fine. It does not, however, state that it otherwise works like standard Weapon Training, in that it states a specific weapon, rather than weapon groups.
Secondly, but not as importantly, Unstoppable Strike is gained at Level 19. It doesn't mention what skill it replaces, but I would presume it replaces Armour Mastery.
