Criterias for summon

Drakina observed in stunned silence as the wolf zombies descended upon the grey wolves. The scene that unfolded was a stark contrast to any battle she might have imagined. The term "brutal" barely seemed to do justice to the ruthless aggression she was witnessing.

The wolf zombies, empowered by their undead nature, displayed a level of almost incomprehensible ferocity. They moved with a relentless drive, each attack more vicious than the last. Their jaws snapped, and claws tore through flesh and bone with a savage intensity. The grey wolves, caught off guard by this unyielding onslaught, tried to retaliate but were quickly overwhelmed.

In the midst of the chaos, Drakina noticed how the wolf zombies seemed utterly immune to pain. Limbs were torn, and wounds were inflicted, yet they continued their assault without a hint of hesitation or self-preservation. This ability to endure and keep fighting despite their grievous injuries, lent them an eerie, nightmarish quality.
