Swamp Palace (A Link Between Worlds)

The is a dungeon in, located in Southern Lorule's Plains of Ruin. It is Lorule's counterpart to the unnamed shrine in Hyrule's Great Swamp, as well as the Dark World's own Swamp Palace. The Hookshot is required to access it, and its boss is Arrghus.

Entrance to the Palace
The entrance to the dungeon is barricaded by a large boulder, which can only be destroyed by the Big Bomb Flower purchased from the scientist south of the Thieves' Town, which will also drain the water filling the dungeon's moat.

Themes and Navigation
Navigation of the Swamp Palace is based on manipulating water currents and water levels, as well as navigating through rooms filled with water. The item around which this dungeon is themed is the Hookshot, which is used to trigger switches, pull Link to distant locations, and even move floating platforms.

The dungeon's miniboss is Gigabari. Aside from taking more damage to kill, it behaves similarly to a regular Bari, and fissions into a large number of Biri when killed.

The boss is Arrghus, who fights similarly to its appearance in. Defeating Arrghus frees Oren.

Items
The Compass can be found in the northern central room of B1. The Big Key is in the central room of the First Floor, on a platform that can be accessed by raising the water level. The flames around the large chest can be extinguished with the Tornado Rod.

This dungeon also houses the Blue Mail, which halves all damage against Link. It is located in the central room of B1, accessible only through lowering the water level in the room to the south. If Link acquires the Blue Mail in Lorule Castle instead, he can return here to find the Red Mail.
