Mana regeneration. That was the biggest problem the spirits are facing: The growing abominations won't be a threat if they could go all out. Here in this suppressed world, that was the only thing holding them back.
Plum alone would've been able to win by using the plants around the world as weapons to wipe out all life. But sadly, she has to keep her mana in check.
As far as all of them knew, there was no way to make Mana out of nothing, unless they got someone like Arad. But even he needs matter to turn into energy, and then the spirits could probably use that to generate mana with some spells.
Each time Plum went into a fight, she was always reminded that if Arad were present, she wouldn't need to fight at all. He would just jump in and clear whatever got in their way.
Gamond was a deadly force in Yog's world, and Arad was a mere human, but in a year, he made her shake her butt for him.
For now, they had to think of something else. Arad isn't to win a war for them.
