The destructive power and combat power of Gods are two distinct concepts.
Some Gods may have moderate destructive power but possess astonishing combat power, while others may lack in combat capability but have terrifying destructive power!
Take Dracula VI and Goddess of fire Glaire for example, if the two were to duel, Glaire would not be a match for Dracula, yet when it comes to destructive power, Dracula cannot compare with Glaire!
If one must describe them, the pair can aptly be depicted as a warrior and a mage — Dracula as the warrior, and Glaire as the mage!
Warriors have strong individual damage, while mages attack over a wide area.
Therefore, describing the destructive power of a God should not solely be based on the damage they cause, but rather by observing their actions and making an overall assessment.
