That's not god-modding, it's power playing, and follows the same principle. Auto-hits and auto-kills are power playng percy, backtrack your post. A mere rockslide will not be enough to kill him if he can think of a way out of it. While you did not make a fatal power play error, you did push time beyond the capable reactions of his character; and that in itself is power playing. The blood suggested that his character didn't have the chance to escape or save himself.
