One move to deal with all situations. If I can blow up the city gates in one shot with an extremely effective large fireball, why do I have to think of so many roundabout ways to breach the city walls?
The mages were called the kings of war for this reason.
With enough strength, mages could always find various ways to tear an opening in the enemy's defenses.
In skirmishes, archers and thieves were the mage's nemeses.
However, it was unlikely that archers and thieves could do anything to target mages on the battlefield who were under heavy protection, and it would be difficult for them to bypass the protective net of the army.
The dumbest and easiest way to fight against mages was to build walls using magic-resistant building materials, but they were expensive and not used in non-border cities or strategically important cities.
