Deep within the forest, [Oblivion] was formed on the ground. There were tress all around them that got destroyed yet Kaguya was still in a good shape. Although she was struggling to maintain the skill where Samael was trapped in.
"I knew it wouldn't be that easy." She thought as beads of sweat formed on her forehead.
Kaguya caught Samael entirely. Aside from the initial impact made by Samael upon hitting the ground, Kaguya immediately casted [Oblivion] below the creature. Deciding to take Samael down before it could even release its full power.
The female elite couldn't cast [Oblivion] while also coating her whole body in the same skill. This is because of the predicament she had with Dark Mana. One which limited her moves, forcing her to cast one spell at a time. Hence, she relied on the split-second interval of Samael crashing down in order to switch [Oblivion] back to an [AoE] skill. Leaving her defenseless.
