Secondary Archetypes Vol I - Variant Multiclassing Archetypes

From publisher blurb:

Issue #105 present 13 new variant multiclassing options as first presented in Paizo's Pathfinder Unchained. Each of these presents a different fighter archetype presented in the form of secondary class abilities replacing feats gained at 3rd level and every 4 levels thereafter. From the Archer to the Weapon Master, this supplement grants you a bit more martial mastery to a character that may sacrifice battlefield finesse for other skills and features.
