If you come across two different Manses with the same hearthstone, do the effects of the two stones add to each other? For example, a Earth Manse gives you a bonus of +2 to any Resistance rolls. So, if you had two of those stones, would you have a +2 or a +4? Plus, with a higher level Manse, you can take a level 3 Manse and have it make three level one stones. If you had it make three of the same stone, would they add to each other? The same with artifacts.
