Many demons were attempting to swarm into the center of the house. In this place, Benjamin was invisible to the demons, thanks to his putsie bag. As they were shooting their weapon's fire into the room, all shots would miss, piercing through the walls and generally messing up the property quite a bit. They weren't prepared for Benjamin being there to defend the others. He would telekinetically mangle them through crushing their skulls, and breaking necks telekinetically. However, the more demon vessels that Benjamin destroyed through his magical powers, the more they would replace the fallen. Eventually, the house was over flowing with dead, and Benjamin would magically conjure an incinerating stream of fire that would not harm Mister Singer's house at all, despite the demon bodies getting annihilated.

However, the stream of demons came at Benjamin, almost like a line of ants. Getting frustrated with having to kill so many enemies, in just two seconds, Benjamin expanded his forcefield to the size of a large wall, he manipulated his mind energy into a hyper speeding full on slam, hitting these demonic vessels hard enough to render them into fine paste. 

He turned his head, noticing that Bobby and Natalia were furiously attempting to defend themselves against mid ranking demons. With several gestures, Benjamin was speaking an incantation with his mouth, lasting several seconds, and conjured a lightning bolt to strike one of the demonic foes from behind.
