Where Is the trial tower? Tanks

In the list is missing Cogoel Cave and you get talking with an NPC of a city that now escapes the name. You can enter after level 100.

Ok thank you so much.

I can not make the screenshot, but in the other entrance to Pheril Town, walking straight up to the sthorehause at the bottom, near a bush there is a hidden path and is in front of the door of the sthorehouse. Sorry my bad english but I'm italian.

In Peril town I found everyone, even the 2 chest treasures. They are located in the other entrance, walk straight to the end and you will find a house without a door, in front there are bushes and a hidden path that will take you to the 2 missing treasures.
