Sunken treasure
Sunken treasure is a chest that can be gathered from the bottom of the ocean by using the Grappling Hook while on the boat over the sea. Sunken treasure can be found by salvaging over light rings that appear in the sea when their corresponding Treasure Chart has been opened or when their corresponding Triforce Chart has been both opened and deciphered by Tingle. Light rings will also appear when defeating Big Octos and certain Gunboats. There are also light rings that appear in the overworld without any charts or enemies--with some only appearing at night--but these will not be randomized on any settings and will only contain Rupees.
Randomizer Settings
There are three settings that will effect whether sunken treasure has progression items: Big Octos and Gunboats, Sunken Treasure (from Triforce Charts), and Sunken Treasure (from Treasure Charts).
Big Octos and Gunboats
Big Octos
** The Big Octo at Two-Eye Reef has a Great Fairy instead of sunken treasure, and will only contain progression items if both Big Octos and Gunboats and Great Fairies are selected.
