What's the longest you've spent camping an item only to leave empty handed?

[Calibretto]

Ohhhh the Burnnoose! Yeah Kellian. I spent many many hours there until i finally got him to drop it. He dropped it the only time I ever saw him spawn too.

In a single session? Probably 20 hours doing rotting skeleton

Over the course of many days? 50ish hours on rotting skeleton

Fuck that skeleton

14 days camping Iksar Berserker Club back in classic. Twice I missed the drop right after I gave up the camp.

Recovered my old account maybe 3 years back and went to Kurns and he was up with the club. Killed that Fucker.

Randomly ran into him in P99 when leveling up and he had the club. Killed that fucker.

Did two camping sessions of 96 hours straight, two weeks in a row with never seeing Undead Lord Grimrot on this server...oh joy.
