What you mean to say is, Oracles eventually become actual seers instead of charlatans hurriedly bashing their opponents over the head with their sticks and proclaiming “The smiting I have foreseen has come to pass!” They’ve become prophets of doom littering the landscape with pillars of stone and four of them guaranteeing the death of anyone they so choose.
I did like how Corruption is essentially pointing and saying you’re now undead and everyone else just believing you.
