Originally posted by the ninjakThe Titans weapons will hurt and eventually take down the balrog. They move at far faster speeds than gandalf was fighting at when taking on the Balrog. Gandalf also had his staff easily broken and as the Grey was easily bested by Saruman.
Gandalf's feats are random being that he's a mage of Old Magic.His feats are comparable to the environment and situation around him. When Gandalf appeared before the Fellowship he made their weapons unuseable and overwhelmed them. Yet when he fought those Orks it was close to being the end of the humans, therefore his faith/magic was weakening.
The magic Gandalf commands isn't a bunch of spells he spams. Lightning bolt, fireball, teleport ect. He asks and he receives what the powers that be give him.
The fight was so devastating that that Gandalf obtained the next level of enlightenment. The Titans are a bunch of high powered animals. They don't have the tools to put it down.The Titans have swords and may be fast but what are they exactly going to do the Balrog?
The Titans would slaughter gandalf or the balrog. Lucky for the Balrog he's much more durable but seeing as how quick and how powerful the Titans were the Balrog quickly loses limbs or his head.
