Golden Lair (Etrian Odyssey IV)Edit

The Golden Lair is the third Labyrinth, located in the Sacred Mountains. It stands apart from the previous two Labyrinths in that it has two entrances: Entrance 1 A/4-1/4; Entrance 2 A/3-1/5. You will need to explore the cave from both entrances to work through the puzzles and make it through to the Boiling Lizard.

You'll need to gather Ice Stakes in order to destroy the glowing scales on every floor and eventually destroy the large pillar of scales on each floor to cool down that floor. You cannot take the Ice Stakes out of the cave or they melt instantly, so you can't sell them unfortunately. These scales will cause you to lose HP every time you step close so be careful, also Ice Stakes are limited so use them wisely.

You should also watch out for the FOEs in this cave, Plated Chasers can slide on the ice thus giving them a huge advantage when the floors are cooled down. When the floors are heated however, they become much less threatening and have to pause every other step to rest.

The monsters also change depending on the temperature, for instance Magma Spawns and Glacier Spawns have 2 forms, a Normal and Melted form. In their melted state they have very little HP and cannot attack you and will only yield one item, unlike their normal forms which will yield 2 items, one regular and one conditional.

Gather PointsEdit

Gathered materials change depending on if the floor is heated or cooled. If it's heated gather points will on yield 1 item, when it's cooled they will yield 2: a common item and a rare item.
