Silas was useless against shadows. His void magic passed right through them.
"Physical attacks don't work!" he yelled as a wolf lunged, its teeth passing through his backpack.
"They're insubstantial!" I realised. "They are made of mana. We need to disrupt the source."
I looked down the hole. The Shaman was chanting, maintaining the spell. He was three floors down. Too far for an axe. Too far for a nail.
I looked at the floor.
The penthouse floor was made of reinforced concrete. Heavy. Solid.
"Silas, get to the balcony!"
"Why?"
"Just move!"
He scrambled away. I ran to the centre of the room, directly above the Shaman. I slammed my hands onto the floor.
[Skill: Deconstruct]
Usually, I broke things down into inventory items. But the System had a toggle. [Mode: Structural Failure].
I didn't absorb the concrete. I simply deleted the rebar holding it together.
The floor beneath my feet turned to dust.
Gravity took over. A ten-ton slab of concrete, the ceiling of the apartment below, detached.
I fell with it.
I saw the Shaman's eyes widen. He looked up just in time to see the ceiling coming down to meet him.
CRUNCH.
The slab crushed him flat. The Shadow Wolves in the penthouse vanished instantly as their summoner became a stain on the lobby floor.
