From publisher blurb:
In this release, we finish a first pass through the Adventurer's Guide with new material for the adept and fighter classes.
Adepts can become Sentries, elite polearm-wielding security experts, who can turn any polearm into a double weapon, use their weapon to vault long distances, and pick out hidden threats with practiced ease.
Fighters can become a Militant, the ultimate generalist. They learn even more combat traditions than most fighters, can switch weapons mid-attack, and eventually even gain the ability to treat weapons as if they possessed properties they do not.
And the new Scrapper synergy feat chain allows you to combine any combination of adept and fighter levels (not just the archetypes in this product) to make the pinnacle of combat training and supernatural athleticism.
