Hey, so two questions.
First one, i noticed that in the water trial you can enter a lower cave where you have one podium for the water core and another for the earth core. The earth core can be used with the corresponding podium but the water core does not react. Is that intended or a Bug?
Second one, The Essence caverns have a locked door that seemingly leads to the back of the Castle. HOWEVER, the key is probably in the bossroom (i have beaten said boss multiple times now to look in peace. there is a box with an arrow atop it so i´m guessing we´re supposed to interact with it and get the key? So i´m guessing, it´s either not a part of the game yet or it´s bugged.
