Scheol statues are terrible for Scheol quest, mainly because of running to that scientist woman in the southwest 20-30 times. I dread Scheol quest 90% for the time the transportation takes, and I always do the keys beforehand + know how to get around the zone pretty well by now.
Even if you think Scheol is pretty, having to run through the same areas over and over like you're running laps through the place will make it ugly real fast.
