The Cave to Rendarak (formerly the Cave to Rhone) is the largest dungeon in Dragon Quest II and the penultimate dungeon in the game. It is located in the south central region of Expanded Alefgard and accessible only via Travel Gate.


The Cave to Rendarak is known for being the most difficult dungeon in the game due to its length, the strong enemies within, and the existence of pitfalls and infinite loops.

The cave is only accessible via a travel gate in Beran that requires the Jailers Key. To open the cave, the Eye of Malroth must be used next to the entrance which is disguised as an impassable mountain tile.


Floor B1 - Soul sigil

Floor 3F - ~1375G, Tombola ticket, Thunderbolt blade

Floor 5F - Thanatos' shield, ~550G, Mad cap, Erdrick's armor

Soul sigil

Bottom right corner of floor B1. But in the iOS remake, it's not located there.

Thunderbolt blade

Find your way to floor 5. Make your way all the way north, then east into the side room; go down the flight of stairs. There is a pitfall in the almost-bottom-leftmost corner of the (huge) room; find and fall in it. You'll land right next to the sword.

Erdrick's armor

Much easier than locating the Thunder Sword, simply find the staircase in the bottom right area of Floor 3 and take the stairs right to the chest.
