-For your tamed animals that can become familiars you could use Olympus and create parallel dimensions where you can keep them and where they can live without risk and freely, you could tame 2 of each type so you always have an increasing number, being familiars they could be stronger thanks to the authority that flows within them and to summon them when he wants and it can also apply to reptiles, in this way he could use them to fight mobs or maybe if they are strong enough to annoy stronger enemies and it could be like the power of Apollo of Voban. -You could make him get closer and closer to the power and ability of the ones from whom he usurped the Authorities, like with a lot of training instead of being able to use master bolt only once a day he could learn to use it more and more times until he no longer has problems summoning it, ultimately it should have the potential to use it as it is used by the original owner and this can be represented by the manifestation of the avatar and practically becoming the god from whom it has usurped authority. -Will you give him the ability to partially transform into a tiger or leopard and become some kind of were creature? -I think you should make it more ruthless. -Could you make an auxiliary chapter where you put the authorities of the subordinate goddesses?
If I remember correctly you could do that he is compatible with the head gods of their pantheon and therefore can obtain more authority from them. For example with Odin he could obtain the authorities: of Asgard which is like that of the court of Zeus, that of magic and the rest you see since he has a lot of them. He could achieve more or less the same things with Ra although you can play on the 3 aspects of him. While with the other gods he could obtain for example: Hades with the authority of God of the Underworld could obtain the powers over the dead and darkness, Ares the authority over war, Hephaestus the authority over metal or technology, Hermes the speed, Kronos on time etc...
