After the Demon Mushroom fended Ban and Eva away, it thought that it was the perfect opportunity to cast its Skill, the Miasma Shower.
It was its trump card, the one it learned after it evolved into a Lord Grade Demon Mushroom from an Elite Grade Demon Mushri.
This would allow it to shoot miasma out of the pores present all around its body. The miasma was not only highly poisonous, it was also highly corrosive, even more corrosive than the Night Worm's in fact.
It can shoot in all directions and the miasma could reach upto 10 meters before it would slow down and drop to the next 3 meters.
The corrosive miasma would also not disappear right away and would actually scatter on the surrounding wet soil, corroding everything that dared step into it.
The only drawback of this skill was that it took 2 seconds to activate it and it would also drain its energy nearly to the bottom.
