Writing The Supernatural - The Pay-Off

Now we have set the scene, created our monster and thoroughly spooked the main character, we need to get to the pay off. The confrontation, the big battle between the main character and the monster. Of course it doesn't have to be an actual battle, it could be psychological in nature, or the main character may just try to outwit them. 
If you have been building up the bad guy, they need to be suitably scary. Of course that doesn't mean they need to have fangs or claws, sometimes the scariest reveals are finding out that someone you thought was the good guy, is actually the bad guy. 
When the bad guy finally shows themselves, it is often when the main character is at their lowest. They have been terrified, driven half mad and they are trapped - literally or figuratively. When confronted, the main character is going to have to fight to survive. 
Your fight scene needs to be satisfying too. Readers want a longer scene, something they can sink their teeth into. Even if the fight itself would play out reasonably quickly, on the page we need to feel like we are there. What is the main character experiencing? How are they feeling? We want to be on the edge of our seats at this moment!
If executed well, the reader will be punching the air when the bad guy is taken down. That isn't always easy to pull off and may require a few drafts to get right. Do get some feedback from others too, make sure that it is a satisfying ending. Satisfying doesn't have to mean happy, but it does have to make sense to the story. 
​Good luck!

Happy writing!
