"Damn it! Domain Declaration is draining my mana too fast!" Elena gritted her teeth, frustration evident on her face.
She wasn't alone—Instructor Samantha was out there, fighting relentlessly, cutting down monsters while shielding civilians. But even with her sheer combat prowess, the sheer number of enemies was overwhelming. If they didn't have to protect the civilians, the battle would have been settled already.
