It's easy to complete yes. But the bugs make it really frustrating. Being one sword away and having it disappear is the stuff of nightmares

Don't let anyone use synth when picking up sword, have sword runner be host, don't use rockets as final hit on sword bearer. And make sure to keep explosive thrallS away from it. I've noticed the blast damage tends to be what pushes the sword to disappear. Now, yes t is a physics glitch that should be patched, if you take precautions, it rarely happens.
