Balrog

It should be noted, however, that Balrogs are incapable of damaging swans, and that swans will deal 100 (50 x ) of damage per hit to a Balrog. This is rather difficult to make happen in practice, however, unless you have the patience to lead a group of swans all the way from Swanfleet or Dor-en-Ernil to Utumno. It should be noted they don't attack the Balrog as they aren't enemies. Balrogs attack every faction except for their own. They also set blocks around themselves on fire, so if in creative mode, don't spawn them in any flammable structure unless you want them to cause some major damage. In Utumno, their fires will also replace nearby non-Utumno blocks, so be careful when building there.
