"I have to cut it off."
I muttered, watching as my trusty rocks crashed about and battered the muck guardian demon. The monster ended up falling, and then thrashed around , as its limbs tore and then regrew, destruction and regeneration both happening at a fast pace.
Its arm fell off, and from the broken ends, vines sprouted and they grew to one another, intending on joining, on becoming one once again.
I willed one of my advanced rocks to strike the fallen arm, and it did so gracefully, turning around and repeatedly striking in succession, until all that remained were battered little vines.
The other part still attached had begun regrowing, its forearm was almost complete, almost whole.
