A hammer blessed by an elf priestess and a holy paladin. You can’t get more divine than that.
This hammer is unique for the fact that instead of being a proper weapon it increases the power of the user’s healing abilities. So, instead of being good for offense this thing is great for supportive characters allowing them to keep everyone that much more healthy.
Who thought hitting people with a hammer would heal them. Oh, sorry, that’s not how it works?
