Underground Reservoir and the Study. The trick to find the area is to find the waterfall in the Underground Reservoir and equip the Undine soul then either the Curly, Manticore or Devil soul to dash through the waterfall. The player will receive the Eversing along the way. On the other side is the door leading to the area. As for the Study, go to the uppermost room in the Forbidden Area to find a switch. Step on the switch to lower down the gate that blocks the passage between the two places. The area also has treasure chests which give off thousands of gold. These enemies can be found here: Alura Une, Harpy, Killer Fish, Flame Demon, Mimic, Gargoyle, Mudman, Dryad, Cagnazzo and Poison Worm.
