As the guardian commander activated the formations, a multitude of spells attacked members of the Dark Dogs. Berta reacted faster than the others. She was going to protect her comrades.
Before the spells reached their target, two skeletons in black armor stood beside Berta, as did all her comrades. They were ready for such a situation. At the same second, Berta cast her most potent protective spell.
A white Magic Circle appeared beneath her feet, from which a glass barrier appeared. Berta and her companions were protected by a dome of particularly strong crystalline glass. Such a barrier could withstand several blows from a second-rank monster. Level one spells could do almost no damage to it.
Nevertheless, there were several second-level formations in this room. With every second level spell hit, many cracks appeared in the barrier and eventually, it began to collapse.
Whoosh.
