Vs wall and cultist

Carlos made his entrance in perfect silence. The wall behind the altar was made of dark wood, but it just … fell apart into freaking grains of matter in an oval six feet high and three across, revealing the young Warden on the other side.
Without ceremony, Carlos pointed at a cultist, muttered a word, and a beam of pale green light struck it in the back. The man-creature simply dissolved into a slurry of water and what looked like powdered charcoal. The young Warden didn’t miss a beat. Before the first cultist was done falling to the floor, he drew his sword and ran it smoothly into the nape of another cultist’s neck. The creature arched for a second and then dropped like a stone, his mouth moving in frantic, silent screaming motions.
