They coordinated with the "captains" that they have assigned whenever even the slightest bit of danger will come. In this way, the chances of losing any Archmages is low to none
Even the desperate Archmages that sacrifice their lives to kill the enemies are not succeeding
Normally, Archmages have a lot of pride. They will fight to the death if needed. Of course, there are still those that will willingly swallow their pride to save themselves
However, none of them were as shameless as the Archmages subordinates of Cairo. He ordered them to teleport away whenever an enemy Archmage sacrifices themselves
In that way, the Archmages use their own life for a "power-up" only for their target to vanish in their eyes. Even if they decided to use their sacrifice to flee, it still wasn't easy
