I have a few characters who are Gifters (people with superpowers) and they're gathering at one of their houses when an argument breaks out. One of the characters, Kevin, gets really worked up and ends up causing a massive explosion which destroys a large part of the surrounding area. However, my problem is that I want some people in the area to survive but I'm not sure how some people die and some people survive. The people in the house survive because one of the other characters, Damien, puts up a forcefield and protects them. I'm really stuck and I was wondering if anyone had any tips?
