Blair witch- Berries Used Against Monster

He filled both hands with berries and squeezed. The juice pressed out between his knuckles, down the back of his hands and his arms.
It felt like power.
Now all he had to do was--
Something struck him on the head, and he dropped like a stone. He rolled quickly to his right, his head ringing, and started to stand. A hand grabbed him by the throat, and lifted him the rest of the way off the ground.
He gasped and reached out to loosen its grip.
One of his hands touched skin.
The other touched wood.
He pressed down hard, feeling the juice of the berries still sticky against his skin; he smelled something burning.
The thing roared with pain and dropped him.
He heard it move away and got back on his feet.
...

The thing loomed over him: he smelled its breath, the scent of the grave, the fetid, moist stench of decay--
He shoved the last of the berries forward and into its mouth.
The thing screamed and shook and fell off him.
It made a gurgling noise in its throat.
And then it was silent.
Crawford got to his feet, wobbled a moment. His head was woozy and throbbing where the thing had hit him.
A cold wind blew, and the mist cleared.
He was on the rock.
Bits and pieces of the abomination Fellowes had built lay in a pile next to him.
Fellowes himself stood outside the circle he had drawn with his old blood, knife in hand.
