Magic

[Arwen Imladris]

What spells did they use? THe only one that I can think of is the one with Arwen at the ford.

Nin o Chithaeglir, lasto beth daer, Rimmo nin Bruinen dan in Ulaer! Nin o Chithaeglir, lasto beth daer, Rimmo nin Bruinen dan in Ulaer! (Waters of the Misty Mountains listen to the great word; flow waters of Loudwater against the Ringwraiths!)

I'm not sure that that is even a spell per say.

The elves might seem like magic, but perhaps they have a craft that is just more advanced than ours?

You could also check out Sam´s "magic" rope? or more idea's.
