Dimension's Keep

Floor 1F: From the entrance, head east. You'll find a locked door with an out-of-reach switch. Go to the dead end to the south, hug the wall below to find a secret passageway leading to an isolated room. Inspect the switch in this room to open the door. Go back and proceed through the now-open door and up the stairs.

Floor 2F: Near the stairs, the path splits. Go west to find a chest containing Dwarven Gloves. Then, take the southward path to the southeast corner. Flip the switch on the wall to open the door near the initial stairs. Hug the corner below this switch to find another secret passageway leading to a secluded chest containing a Laevateinn. Return to the path split and head north through the newly opened door and up the stairs.

Floor 3F: Head east to find a chest with a Barrier Shroud. Continue to the bottom-right corner to find a secret passageway leading south to an isolated room with a switch. Activate this switch to open a door near the center of the floor. Return to the stairs and head south. Before turning the corner, go west to find the opened door. A chest containing an Elixir is to the south. Before passing through the door, continue along the path to the southeast corner. Go right into the corner to find a secret passageway going south. Where the path seems to stop, head west to find an unseen chest.

Boss: Jabberwock (Level 80, 200,000 HP, Weakness: Light, Dragon): This dark dragon uses Bite, Fearsome Breath (inflicts dark damage and Dread), and Evil Eye (inflicts weakness to dark attacks). To counter, equip Courage Rings (available from Hartschild), group-cast Elemental Barrier with Prescience to override Evil Eye. Avoid Dark Mirror as Jabberwock absorbs dark damage. Use physical attacks, preferably light-based or with a greatsword like the Excalibur. The Black Mage's Pierce Magic Defence ability can also be used if affordable.

Floor 3F (Continued): After defeating Jabberwock, return to the center of the floor and go through the door opened earlier. Follow the corridor to the south-most dead end. A secret passageway below leads to an isolated room on the left. Pull the switch here to open the locked door northwest from the center. Return along the corridor and descend the stairs in the northwest corner.

Floor 1F and 2F (Again): On Floor 2F, head south from the stairs. Before the dead end, turn west for a chest containing a Black Belt. Continue to the dead end and explore the bottom-right corner to find a secret passageway. Follow this path west to the southwest corner. Hug the bottom-right corner here to find another hidden path leading to a switch in an isolated room on the right. This switch opens the door in the northwest corner, granting access to the stairs. Finally, on Floor 1F, in the northwest corner, you will find a chest containing a Ribbon, which negates all common status ailments.
