How does the Reinforcement Rune hardness cap interact with bonuses from champion shield ally, Dwarven Reinforcement, Everstand Stance, and Emblazon Armament? I seems like, in the early to mid game, you could have a higher hardness without using magic. A 7th level Dwarven Champion multi-Cleric master Crafter could make a fortress shield with a hardness 12. This is all with standard materials and no magic. Am I missing something?
