You are no longer a 'minor' god. You are a Major God on the level of Ares, able to even become more powerful than Zeus.
Your divine physiology is improved. Now, the only way you can even take damage is if the source has any divinity. Without anti-immortal or anti-divine weaponry, mortals are completely incapable of damaging you.
A demigod can hurt you, but even they are weak to your power.
Your strength grows leaps and bounds, able to temporarily keep all of Creation above your head, a strength immeasurable.
You gain significant protection against Fate, Time, and Destiny.
Your power grows significantly with worship.
Attacks that target your soul are significantly weaker and your powers are incredibly hard to copy or take. Your domain grows significantly, becoming a Major Domain with two secondary minor domains.
Your shapeshifting increases significantly, allowing you to grow to sizes surpassing modern day skyscrapers. On top of all of this, you gain a weapon or pair of weapons that embody your domain. Hades had the Claws of Hades, allowing him to rip people's souls out of their bodies, even Titans. Using this, he could also summon souls anywhere from the claws.
