Adventures 140 U 112 R 23 E 5 L 0 Side note: I lost some data due to a crash (blue screen of death), but it was about the same as what I'm reporting. My scratch paper notes didn't crash, so I know that I've had 0 legendaries in the past 232 adventures. Also 0 legendaries in 500 18gp chests, and 0 legendaries in 10 days of speed farming. This has nothing specifically to do with upgrades in the club slot of final chests, but it does show how depressing tracking can become. I've found plenty of stuff to sell, though, and I'm back over 100k gp. Just wish I had something good to spend it on. [/whining]
Sounds like you should be buying more than 500 18gp chests at a time. Also, unless you are doing it for no other reason than pure science and data collection, I would stop tracking my loot drops if they were that depressing.
Usually you get one L every 3-4k gold. 500 chests is 8k, he allready bought more than a regular chests fever spread.
Lately I've been tracking for this thread. My overall results didn't seem good either, so I tracked total legendary drops for a while to see if it was as bad as it seemed. It was. I've also been tracking rarities in 18 gp chests on a sporadic basis. Sometimes I'll get a lucky drop, but I normally just convert 9k gp to about 1.3k gp and have a lot of excess to sell off manually. I'd buy more if we had a Sell Excess button. I'm doing it for data collection, but I should probably take a break anyway.
I feel your pain (but nowhere near the scale) of not having a Sell Excess button. Either way, you seem to have the very, very short end of the stick when it comes to luck in this game recently, and hopefully that pattern doesn't continue for very long.
