In most parts of the world, wealth is the cornerstone of mighty divine power, generally from mid-tier divine power upwards.
The fact that the goddess Waukeen struggles doesn't mean the divine position of wealth does.
The core divine positions of Waukeen are wealth, money, and trade, whereas the golden decree scepter in Duncan's hand is infused with the power of the 'money' domain.
This blow of the 'big money stick' struck down, making even the ghoul king Doreson doubt existence!
One could say the factor limiting Duncan's combat power now is purely that the goddess of wealth, Waukeen, has not fully developed the potential of the divine position of money and wealth. If it were a world with a higher civilization level, perhaps akin to modern magic civilization, then the power of money and wealth could instantly knock dead the lower demon lord in front.
All that nonsense about love and joy, in the face of the god of wealth, everything has to stand aside.
