Fighting the Reed Devil in Crimson Desert is the first boss that might potentially challenge you, especially if you didn't find Hornsplitter all that hard. Part of the difficulty of this fight is that you come to it after having fought your way through a whole army of the Reed Devil's minions as you pursued him from the Reedfield Graves.
You finally catch up to him at Reedwind Valley—a pretty field of flowing grass—which is to be your arena. I'll run through some tips to prepare for the Reed Devil fight (including a nearby fast travel point so you can return later), plus a handy trick to deal with his annoying clones and totems before the second phase.
