multiple attempts, sure. But over 200 deaths (obviously a hyperbole, I hope) Is a little ridiculous, especially cause you don't even have to go all that fast and the path is relatively straightforward
yea, most of the mysteries since PoF have been extremely gimmicky. Even most of the IBS stuff has 0 use outside of those maps.
The only EoD Masteries that have any actual use outside of those maps are the rescue stuff, ExP Buff and the turtle.
Maaaaaybe the skiff if you're hardcore into fishing or RP
world record is meaningless cause that's the optimum....last time I did it on a new character with all mounts, but not level boosts, it took me about 35 hours, so roughly one hour per map, without hearts it was closer to 15 minutes per map
