<span style="color:#323232;">Name omitted to respect privacy but if you really want to know they're easy to find on both Lalachievements and FFXIVcollect. Here's a picture of what this insanity includes:

</span><span style="color:#323232;">
</span><span style="color:#323232;"> Fully cleared all treasure dungeons at least 20 times, including the Hidden Canals of Uznair, which was a notoriously impossible achievement for many years and requires about 2000 Thief's Maps on average.

Can confirm most of these are mind numbingly boring and mundane. I could barely get through the slog of ONE ARR and HW relic for starters. I’m also not ashamed to admit I’ve paid for bot programs to avoid doing a few of these tasks because of how tedious they can be. (Even just normally. I never went out of my way to try and complete any of these achievements.)
