Seeing the opening, Elvira seized the opportunity. A magic circle shimmered in the air as she swiftly infused multiple spells into the wall.
Ten white gemstones floated in the air, their surfaces pulsing like captured stars. They surged forward, embedding themselves into the fortress walls, fueling the massive magic circle. The runes carved into the structure flared violently, drinking in the power as Elvira layered her incantations, her voice ringing clear over the battlefield.

The first spell anchored itself into the walls, weaving an enchantment that retaliated against any attack aimed at the wall or its defenders.
"Resonant Pulse!"
A secondary layer intertwined with the first, ensuring that not just one, but multiple reflections could trigger at the same time—a chain reaction of counterattacks.
"Adamant Bastion!"
The final layer solidified into an impenetrable shield, forming an autonomous defense system that activated on impact.
