She wasn't someone to be treated lightly when being enraged!
So, everyone just waited, while watching her skeletons really bully the monsters. She didn't summon even a single skeleton since the last three giants were killed.
She sighed, as this would be a better scene if she had her huge three giants already. But she wasn't that depressed, as she already had many giant skeletons summoned from the lord monsters.
As for the lord monsters killed here, she glanced at them with regret, while finally looking away to resist her urge to summon skeletons from them.
After all she killed twenty lords in this area, and this wasn't a small number for her after all.
However when she killed them, the counter she had in front of her had moved by a visible amount, making her let go of any inner desire to turn them into skeletons.
She had to sacrifice them so she could summon her biggest three giants!
