The Lord of the Rings: The Third Age (2004)
WHAT ARE THEY: Balrogs are fiery demonic creatures who were once angelic beings (Maiar) that were seduced to the dark side by the first Dark Lord - Melkor (AKA Morgoth).
STRENGTHS: *very resistant bodies, seemingly made out of pure fire and shadow *large size *great physical srength *ability to use flaming weapons
WEAKNESSES: *their flames can be quenched with a lot of water
HOW TO HUNT THEM: You have to be a very powerful being, in order to defeat a Balrog. Gandalf (Maiar), Echtelion and Glorfindel (Elves) have each killed a Balrog, but all three of them have also died in the process. So, if you want to kill one of those demons, you'll need to have an enchanted weapon, a 100 buckets of water, and be ready for self-sacrifice.
