Callista felt an unsettling surge of mana enveloping her enemy. Eren's Death mana radiated outward, exerting its influence on the verdant vegetation that had flourished around him under the effects of Nature mana.
From the very ground, several skeletons of fallen Amazonian warriors emerged, brought back to a semblance of life by Eren's necromantic powers. Alongside them stood the plant monsters he had previously slain, their allegiance now shifted as they were reanimated with the potent touch of Death mana.
The creatures summoned by Eren were shrouded in the sinister aura of Death, a formidable counter to Callista's Nature mana. Their eerie shrieks filled the air, a chilling symphony that signaled the commencement of their relentless assault on their full-of-life foes.
