Didn't like Hades. That being said, unlocking all of the mirror talents and using some good ones, in particular gaining more health when you gain darkness is nice. Diamonds are strictly useful in the beginning works contracts as you can put more health fountains in each world. After that, lose their shine.
Using the weapon you are most comfortable with and then getting some good boons is the way to go. You can bring up the boon list which can give you hints on how to get more, and you can do some interesting stuff with the different combinations you get.
