The celestial nighthawk modifies the golden gun super to be one shot instead of multiple. I was thinking if titans that use the sunbreaker subclass had a similar exotic, then that would be interesting. Instead of throwing multiple hammers, you throw one that either creates a massive explosion with aoe if you're using the top tree or it creates a massive sunspot that lasts longer, deals more damage over time and charges abilities faster than normal if you're using the bottom tree.
