I looted 2 World Eater Blade and a Silver Freeze before I found My first lost sword using grand Blunderbuss at thrall room. I would give you a lot of tips where to find it but honestly....... Lost sword is VARY random and indifferent to find then any other legendary in my opinion. Each time I found it ( Which I have found it 3 times ) I just logged in within first 100 enemies I found it. I also found 1 of them at sea in a loot chest Which was my first run that day.
But if I was going to give you advice on finding lost sword I recommend reading my guide to looting and give it a shot. My guide has helped 5 people find Lost Sword, and yes I am vary proud of it.
If you do read my guide please leave a comment letting my know what you think of it.
