Bloodstained: Ritual of the Night has many treasures for players to locate and claim, including a large number of underwater chests. These can only be opened once players have acquired a specific shard that allows them to sink to the bottom of the water. Of course, the shard can only be obtained by defeating a boss hiding out in the desert. Here's where to find the shard needed to open underwater chests.
How to open underwater chests in Bloodstained: Ritual of the Night
To open underwater chests in Bloodstained: Ritual of the Night, players need the Deep Sinker shard. This shard is found in the furthest reaches of the Hidden Desert, in a room that is only accessible after a hidden boss fight. Find its location highlighted on the map image below.
Near the tail end of the Hidden Desert, players will come upon an elevator. Midway up the shaft is a door that will only open once the boss in the room above has been defeated. We won't spoil the details here, but after the battle has been won, ride the elevator back down one level to discover the passage is no longer blocked. Within, players will find a crystal they can break to claim the Deep Sinker shard.
With the Deep Sinker shard equipped, players will simply sink to the bottom of any watery area, allowing them to open any and all underwater chests. Do keep in mind that the Aqua Stream shard will no longer propel the hero underwater once Deep Sinker is equipped, though the ability can be toggled on and off within the menu. Underwater movement is also severely limited, though it's possible to upgrade mobility by enhancing the shard itself.
It's easy to open underwater chests in Bloodstained: Ritual of the Night once the Deep Sinker shard has been found and equipped. Be prepared for a fight in the Hidden Desert, but once the battle is over, the door to the shard will be unlocked.
