I've been looking at building a Cavalier, and checking out the archetypes made me think of an interesting question. Are the Beast Rider and Standard Bearer archetypes compatible? The only cross over between the two is the Mount class feature, which Standard Bearer moves without altering. I'm just curious, because I'm not interested in mounted combat, and by combining the two, you get a mildly useful ability (Banner) early, and don't receive your mount until it can actually be something other than a horse.
Could this be a potentially PFS legal alternative to the Hound archetype from RPG superstar?
If an archetype changes a class ability, even slightly, they are not compatible with other archetypes that change that ability.
It will not be PFS legal. Just play a Halfling to get a doggy if you want that hound master.
