Probably Etheryn's 'Wyldkin' set would have an better sync. with her '
Toxic Shock' Power if her 'At-Will' Power was switched to an Power that would give her the ability to have a chance in poisoning the target instead of the current defensive '
Earthward' one, that doesn't really sit well in an damage role set.
Or create a new/rename the '
Frozen Flower' Perk that would be named 'Poisonous Flower', and give it the ability to have a chance in poisoning the target/targets instead of dealing frost damage (i don't remember if poisons can stack aswell, but poisoning with the
Miasma Encounter power than could stack with already existing poisons).
Yet changing '
Earthward' for a better one would also be an must, probably one that would give 'Obscure' if too much threat was being generated.
