My Lands: Black Gem Hunting

10/hour is definitely not enough. It doesn't allow total safety against more than 1 player. My suggestion is to have a set that boosts the temple even more. It can also be specialization, maybe add some temple points boost to the cleric. It can be specific arts or set bonus. Or why not even regular 1-7, perfect, Godly level of buildings. Then you get exceptional bonus.

Thanks
