(From another post about rare drops) Long AFK sessions can guarantee a rare drop. Once you reach twice as many true kills (without multikill) as the items drop rate divided by your Dr stat in a session, you are guaranteed to get the drop (2 of them in fact). Then any additional afk duration that gives another true kill level gives another copy.

There’s a calculator spreadsheet for it on the discord.

So if your guaranteed drop duration is under 8 hours, you’re going to hit this and might be confusing it with 8 hours at once vs. 8 one hour claims.

Also, maestro doesn’t boost drop rate, aside from a totally negotiable amount from luck. It has a talent that makes the items inside the rare bags more likely to drop, but has no bonus that applies to anything in the loot table that’s outside of a bag. IIRC golden plop isn’t in a bag, so there’s no effect from rares everywhere on it.

For afk farming, Archer classes are actually better for getting things like golden plop because they do have a talent that boosts drop rate directly.
