Thanks for the kind review, Ssalarn.
Arbiter's Decree is one of the class features I'm most satisfied with. As excited as I was to tackle a spell-less inquisitor, the Arbiter almost steals the show as far as this product goes, despite taking up less space.
I bumped into the same observation. Your spell-less Ranger archetypes are some of my favorite third party supplements, and I was super excited to see the addition of a spell-less Inquisitor. But the moment I checked out the Arbiter I immediately had visions of slapping on the Black Powder Inquisiton for a Wyatt Earp style lawman. I'm picturing the movie Tombstone, and Arbiter's Decree being one of those moments where he yells something like "Skin that smoke-wagon!" and the enemy is so overcome by his sheer force of personality that they're still stammering and fumbling for their weapon when the Arbiter starts laying the smack down.
