How strong is a full-time mage's forbidden spell? The strongest in the world

Answer 1

There was no definite answer to the question of how strong a full-time mage's forbidden spell was because the strength of a full-time mage's forbidden spell depended on many factors such as the full-time mage's skills, the effect of the forbidden spell, the enemy's ability, and so on.

In some novels, the power of a full-time mage's forbidden spell was so high that it could cause great damage and even destroy a city. In other novels, the strength of a full-time mage's forbidden spell was very weak and could only cause some light damage.

In short, the strength of a full-time mage's forbidden spell depended on the plot and setting of the novel. There was no fixed standard to measure its strength.
