piece of ancient weapon

[SellSword]

I bought a piece from someone and had it in my house when I found the second piece myself. I think it's just dumb luck for everything.

If it's a low % of finding one then most likely you won't find one for awhile. It's different from something like trying to get a drop from mobs because you can fight hundreds or thousands of mobs in a day which gives you more chances. The ancient weapon is like fighting one lightning bee in a day and hoping for a sting to drop, then trying just one bee the next day.
