Domain Disadvantage.

Her concept of Enthralling Flower can't enslave Origin gods but it can reduce their fighting strength and can render them powerless in large enough amount. She is so powerful that it can affect numerous Origin gods at once. She becomes a terrifying force to deal with when combined with her army. 

Her concept gets to be displayed fully in wars but now she is defenseless and powerless to resist. The beads ate her pollen eagerly without any effect and were already eating into her. She can't even summon her slaves to stall the beads of devouring. She will be dead in moments. 

The last one is the toughest one here. His concept The Father Of Treants makes him a giant walking tree. He is very slow but he is very strong. That strength of his is useless against the beads of devouring. Hitting them is a waste since they are too small individually.
