first of all , you are exagerating. At best she replaces 2 mages. For example awakened odette does around 700 without prince buff.It should go around 850-900 with it , without any other team multipliers (like uzume/aria/etc). Considering the one in the image was doing 2250 at max lvl with probably the best prince title possible , that means she can replace 2 odettes. That is insane dps i agree , but then again , u don't need to use mages. You could easily place a solano , which also has great dps and true damage. The more resistance the enemies have , the better solano becomes.

Meanwhile gellius doesn't care what resistance his enemies have....nor what they attack him with seeing as he gains a bunch of mr alongside his huge hp pool and great defense.


Bottom line : gellius is good vs all forms of attackers. Nadia's offense is again situational , depending on the enemies resistances.
